The below diagram shows how they relate. + + + +### `langchain-core` +This package contains base abstractions of different components and ways to compose them together. +The interfaces for core components like LLMs, vectorstores, retrievers and more are defined here. +No third party integrations are defined here. +The dependencies are kept purposefully very lightweight. + +### `langchain-community` + +This package contains third party integrations that are maintained by the LangChain community. +Key partner packages are separated out (see below). +This contains all integrations for various components (LLMs, vectorstores, retrievers). +All dependencies in this package are optional to keep the package as lightweight as possible. + +### Partner packages + +While the long tail of integrations are in `langchain-community`, we split popular integrations into their own packages (e.g. `langchain-openai`, `langchain-anthropic`, etc). +This was done in order to improve support for these important integrations. + +### `langchain` + +The main `langchain` package contains chains, agents, and retrieval strategies that make up an application's cognitive architecture. +These are NOT third party integrations. +All chains, agents, and retrieval strategies here are NOT specific to any one integration, but rather generic across all integrations. + +### [LangGraph](/docs/langgraph) + +Not currently in this repo, `langgraph` is an extension of `langchain` aimed at +building robust and stateful multi-actor applications with LLMs by modeling steps as edges and nodes in a graph. + +LangGraph exposes high level interfaces for creating common types of agents, as well as a low-level API for constructing more contr + +### [langserve](/docs/langserve) + +A package to deploy LangChain chains as REST APIs.

To highlight a few of the reasons you might want to use LCEL: + +**First-class streaming support** +When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. + +**Async support** +Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langsmith) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server. + +**Optimized parallel execution** +Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency. + +**Retries and fallbacks** +Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost. + +**Access intermediate results** +For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used to let end-users know something is happening, or even just to debug your chain. You can stream intermediate results, and it’s available on every [LangServe](/docs/langserve) server. + +**Input and output schemas** +Input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe. + +[**Seamless LangSmith tracing**](/docs/langsmith) +As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step. +With LCEL, **all** steps are automatically logged to [LangSmith](/docs/langsmith/) for maximum observability and debuggability. + +[**Seamless LangServe deployment**](/docs/langserve) +Any chain created with LCEL can be easily deployed using [LangServe](/docs/langserve). + +### Interface + +To make it as easy as possible to create custom chains, we've implemented a ["Runnable"](https://api.python.langchain.com/en/stable/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable) protocol. Many LangChain components implement the `Runnable` protocol, including chat models, LLMs, output parsers, retrievers, prompt templates, and more. There are also several useful primitives for working with runnables, which you can read about below. + +This is a standard interface, which makes it easy to define custom chains as well as invoke them in a standard way. +The standard interface includes: + +- [`stream`](#stream): stream back chunks of the response +- [`invoke`](#invoke): call the chain on an input +- [`batch`](#batch): call the chain on a list of inputs + +These also have corresponding async methods that should be used with [asyncio](https://docs.python.org/3/library/asyncio.html) `await` syntax for concurrency: + +- `astream`: stream back chunks of the response async +- `ainvoke`: call the chain on an input async +- `abatch`: call the chain on a list of inputs async +- `astream_log`: stream back intermediate steps as they happen, in addition to the final response +- `astream_events`: **beta** stream events as they happen in the chain (introduced in `langchain-core` 0.1.14) + +The **input type** and **output type** varies by component: + +| Component | Input Type | Output Type | +| --- | --- | --- | +| Prompt | Dictionary | PromptValue | +| ChatModel | Single string, list of chat messages or a PromptValue | ChatMessage | +| LLM | Single string, list of chat messages or a PromptValue | String | +| OutputParser | The output of an LLM or ChatModel | Depends on the parser | +| Retriever | Single string | List of Documents | +| Tool | Single string or dictionary, depending on the tool | Depends on the tool | + + +All runnables expose input and output **schemas** to inspect the inputs and outputs: +- `input_schema`: an input Pydantic model auto-generated from the structure of the Runnable +- `output_schema`: an output Pydantic model auto-generated from the structure of the Runnable + +## Components + +LangChain provides standard, extendable interfaces and external integrations for various components useful for building with LLMs. +Some components LangChain implements, some components we rely on third-party integrations for, and others are a mix. + +### LLMs +Language models that takes a string as input and returns a string. +These are traditionally older models (newer models generally are `ChatModels`, see below). + +Although the underlying models are string in, string out, the LangChain wrappers also allow these models to take messages as input. +This makes them interchangeable with ChatModels. +When messages are passed in as input, they will be formatted into a string under the hood before being passed to the underlying model. + +LangChain does not provide any LLMs, rather we rely on third party integrations. + +### Chat models +Language models that use a sequence of messages as inputs and return chat messages as outputs (as opposed to using plain text). +These are traditionally newer models (older models are generally `LLMs`, see above). +Chat models support the assignment of distinct roles to conversation messages, helping to distinguish messages from the AI, users, and instructions such as system messages. + +Although the underlying models are messages in, message out, the LangChain wrappers also allow these models to take a string as input. +This makes them interchangeable with LLMs (and simpler to use). +When a string is passed in as input, it will be converted to a HumanMessage under the hood before being passed to the underlying model. + +LangChain does not provide any ChatModels, rather we rely on third party integrations. + +We have some standardized parameters when constructing ChatModels: +- `model`: the name of the model + +ChatModels also accept other parameters that are specific to that integration. + +### Function/Tool Calling + +:::info +We use the term tool calling interchangeably with function calling. Although +function calling is sometimes meant to refer to invocations of a single function, +we treat all models as though they can return multiple tool or function calls in +each message. +::: + +Tool calling allows a model to respond to a given prompt by generating output that +matches a user-defined schema. While the name implies that the model is performing +some action, this is actually not the case! The model is coming up with the +arguments to a tool, and actually running the tool (or not) is up to the user - +for example, if you want to [extract output matching some schema](/docs/tutorial/extraction/) +from unstructured text, you could give the model an "extraction" tool that takes +parameters matching the desired schema, then treat the generated output as your final +result. + +A tool call includes a name, arguments dict, and an optional identifier. The +arguments dict is structured `{argument_name: argument_value}`. + +Many LLM providers, including [Anthropic](https://www.anthropic.com/), +[Cohere](https://cohere.com/), [Google](https://cloud.google.com/vertex-ai), +[Mistral](https://mistral.ai/), [OpenAI](https://openai.com/), and others, +support variants of a tool calling feature. These features typically allow requests +to the LLM to include available tools and their schemas, and for responses to include +calls to these tools. For instance, given a search engine tool, an LLM might handle a +query by first issuing a call to the search engine. The system calling the LLM can +receive the tool call, execute it, and return the output to the LLM to inform its +response. LangChain includes a suite of [built-in tools](/docs/integrations/tools/) +and supports several methods for defining your own [custom tools](/docs/how_to/custom_tools). + +There are two main use cases for function/tool calling: + +- [How to return structured data from an LLM](/docs/how_to/structured_output/) +- [How to use a model to call tools](/docs/how_to/tool_calling/) + + +### Message types + +Some language models take a list of messages as input and return a message. +There are a few different types of messages. +All messages have a `role`, `content`, and `response_metadata` property. + +The `role` describes WHO is saying the message. +LangChain has different message classes for different roles. + +The `content` property describes the content of the message. +This can be a few different things: + +- A string (most models deal this type of content) +- A List of dictionaries (this is used for multi-modal input, where the dictionary contains information about that input type and that input location) + +#### HumanMessage + +This represents a message from the user. + +#### AIMessage + +This represents a message from the model. In addition to the `content` property, these messages also have: + +**`response_metadata`** + +The `response_metadata` property contains additional metadata about the response. The data here is often specific to each model provider. +This is where information like log-probs and token usage may be stored. + +**`tool_calls`** + +These represent a decision from an language model to call a tool. They are included as part of an `AIMessage` output. +They can be accessed from there with the `.tool_calls` property. + +This property returns a list of dictionaries. Each dictionary has the following keys: + +- `name`: The name of the tool that should be called. +- `args`: The arguments to that tool. +- `id`: The id of that tool call. + +#### SystemMessage + +This represents a system message, which tells the model how to behave. Not every model provider supports this. + +#### FunctionMessage + +This represents the result of a function call. In addition to `role` and `content`, this message has a `name` parameter which conveys the name of the function that was called to produce this result. + +#### ToolMessage + +This represents the result of a tool call. This is distinct from a FunctionMessage in order to match OpenAI's `function` and `tool` message types. In addition to `role` and `content`, this message has a `tool_call_id` parameter which conveys the id of the call to the tool that was called to produce this result. + + +### Prompt templates +Prompt templates help to translate user input and parameters into instructions for a language model. +This can be used to guide a model's response, helping it understand the context and generate relevant and coherent language-based output. + +Prompt Templates take as input a dictionary, where each key represents a variable in the prompt template to fill in. + +Prompt Templates output a PromptValue. This PromptValue can be passed to an LLM or a ChatModel, and can also be cast to a string or a list of messages. +The reason this PromptValue exists is to make it easy to switch between strings and messages. + +There are a few different types of prompt templates + +#### String PromptTemplates + +These prompt templates are used to format a single string, and generally are used for simpler inputs. +For example, a common way to construct and use a PromptTemplate is as follows: + +```python +from langchain_core.prompts import PromptTemplate + +prompt_template = PromptTemplate.from_template("Tell me a joke about {topic}") + +prompt_template.invoke({"topic": "cats"}) +``` + +#### ChatPromptTemplates + +These prompt templates are used to format a list of messages. These "templates" consist of a list of templates themselves. +For example, a common way to construct and use a ChatPromptTemplate is as follows: + +```python +from langchain_core.prompts import ChatPromptTemplate + +prompt_template = ChatPromptTemplate.from_messages([ + ("system", "You are a helpful assistant"), + ("user", "Tell me a joke about {topic}" +]) + +prompt_template.invoke({"topic": "cats"}) +``` + +In the above example, this ChatPromptTemplate will construct two messages when called. +The first is a system message, that has no variables to format. +The second is a HumanMessage, and will be formatted by the `topic` variable the user passes in. + +#### MessagesPlaceholder + +This prompt template is responsible for adding a list of messages in a particular place. +In the above ChatPromptTemplate, we saw how we could format two messages, each one a string. +But what if we wanted the user to pass in a list of messages that we would slot into a particular spot? +This is how you use MessagesPlaceholder. + +```python +from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder +from langchain_core.messages import HumanMessage + +prompt_template = ChatPromptTemplate.from_messages([ + ("system", "You are a helpful assistant"), + MessagesPlaceholder("msgs") +]) + +prompt_template.invoke({"msgs": [HumanMessage(content="hi!")]}) +``` + +This will produce a list of two messages, the first one being a system message, and the second one being the HumanMessage we passed in. +If we had passed in 5 messages, then it would have produced 6 messages in total (the system message plus the 5 passed in). +This is useful for letting a list of messages be slotted into a particular spot. + +An alternative way to accomplish the same thing without using the `MessagesPlaceholder` class explicitly is: + +```python +prompt_template = ChatPromptTemplate.from_messages([ + ("system", "You are a helpful assistant"), + ("placeholder", "{msgs}") # <-- This is the changed part +]) +``` + +### Example Selectors +One common prompting technique for achieving better performance is to include examples as part of the prompt. +This gives the language model concrete examples of how it should behave. +Sometimes these examples are hardcoded into the prompt, but for more advanced situations it may be nice to dynamically select them. +Example Selectors are classes responsible for selecting and then formatting examples into prompts. + + +### Output parsers + +:::note + +The information here refers to parsers that take a text output from a model try to parse it into a more structured representation. +More and more models are supporting function (or tool) calling, which handles this automatically. +It is recommended to use function/tool calling rather than output parsing. +See documentation for that [here](/docs/concepts/#function-tool-calling). + +::: + +Responsible for taking the output of a model and transforming it to a more suitable format for downstream tasks. +Useful when you are using LLMs to generate structured data, or to normalize output from chat models and LLMs. + +LangChain has lots of different types of output parsers. This is a list of output parsers LangChain supports. The table below has various pieces of information: + +**Name**: The name of the output parser + +**Supports Streaming**: Whether the output parser supports streaming. + +**Has Format Instructions**: Whether the output parser has format instructions. This is generally available except when (a) the desired schema is not specified in the prompt but rather in other parameters (like OpenAI function calling), or (b) when the OutputParser wraps another OutputParser. + +**Calls LLM**: Whether this output parser itself calls an LLM. This is usually only done by output parsers that attempt to correct misformatted output. + +**Input Type**: Expected input type. Most output parsers work on both strings and messages, but some (like OpenAI Functions) need a message with specific kwargs. + +**Output Type**: The output type of the object returned by the parser. + +**Description**: Our commentary on this output parser and when to use it. + +| Name | Supports Streaming | Has Format Instructions | Calls LLM | Input Type | Output Type | Description | +|-----------------|--------------------|-------------------------------|-----------|----------------------------------|----------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| [JSON](https://api.python.langchain.com/en/latest/output_parsers/langchain_core.output_parsers.json.JsonOutputParser.html#langchain_core.output_parsers.json.JsonOutputParser) | ✅ | ✅ | | `str` \| `Message` | JSON object | Returns a JSON object as specified.

It is less powerful than other output parsers since it only allows for fields to be strings. This can be useful when you are working with smaller LLMs. | + +### Chat History +Most LLM applications have a conversational interface. +An essential component of a conversation is being able to refer to information introduced earlier in the conversation. +At bare minimum, a conversational system should be able to access some window of past messages directly. + +The concept of `ChatHistory` refers to a class in LangChain which can be used to wrap an arbitrary chain. +This `ChatHistory` will keep track of inputs and outputs of the underlying chain, and append them as messages to a message database +Future interactions will then load those messages and pass them into the chain as part of the input. + +### Document + +A Document object in LangChain contains information about some data. It has two attributes: + +- `page_content: str`: The content of this document. Currently is only a string. +- `metadata: dict`: Arbitrary metadata associated with this document. Can track the document id, file name, etc. + +### Document loaders + +These classes load Document objects. LangChain has hundreds of integrations with various data sources to load data from: Slack, Notion, Google Drive, etc. + +Each DocumentLoader has its own specific parameters, but they can all be invoked in the same way with the `.load` method. +An example use case is as follows: + +```python +from langchain_community.document_loaders.csv_loader import CSVLoader + +loader = CSVLoader( + ... # <-- Integration specific parameters here +) +data = loader.load() +``` + +### Text splitters + +Once you've loaded documents, you'll often want to transform them to better suit your application. The simplest example is you may want to split a long document into smaller chunks that can fit into your model's context window. LangChain has a number of built-in document transformers that make it easy to split, combine, filter, and otherwise manipulate documents. + +When you want to deal with long pieces of text, it is necessary to split up that text into chunks. As simple as this sounds, there is a lot of potential complexity here. Ideally, you want to keep the semantically related pieces of text together. What "semantically related" means could depend on the type of text. This notebook showcases several ways to do that. + +At a high level, text splitters work as following: + +1. Split the text up into small, semantically meaningful chunks (often sentences). +2. Start combining these small chunks into a larger chunk until you reach a certain size (as measured by some function). +3. Once you reach that size, make that chunk its own piece of text and then start creating a new chunk of text with some overlap (to keep context between chunks). + +That means there are two different axes along which you can customize your text splitter: + +1. How the text is split +2. How the chunk size is measured + +### Embedding models +The Embeddings class is a class designed for interfacing with text embedding models. There are lots of embedding model providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them. + +Embeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space. + +The base Embeddings class in LangChain provides two methods: one for embedding documents and one for embedding a query. The former takes as input multiple texts, while the latter takes a single text. The reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself). + +### Vectorstores +One of the most common ways to store and search over unstructured data is to embed it and store the resulting embedding vectors, +and then at query time to embed the unstructured query and retrieve the embedding vectors that are 'most similar' to the embedded query. +A vector store takes care of storing embedded data and performing vector search for you. + +Vectorstores can be converted to the retriever interface by doing: + +```python +vectorstore = MyVectorStore() +retriever = vectorstore.as_retriever() +``` + +### Retrievers +A retriever is an interface that returns documents given an unstructured query. +It is more general than a vector store. +A retriever does not need to be able to store documents, only to return (or retrieve) them. +Retrievers can be created from vectorstores, but are also broad enough to include [Wikipedia search](/docs/integrations/retrievers/wikipedia/) and [Amazon Kendra](/docs/integrations/retrievers/amazon_kendra_retriever/). + +Retrievers accept a string query as input and return a list of Document's as output. + +### Advanced Retrieval Types + +LangChain provides several advanced retrieval types. A full list is below, along with the following information: + +**Name**: Name of the retrieval algorithm. + +**Index Type**: Which index type (if any) this relies on. + +**Uses an LLM**: Whether this retrieval method uses an LLM. + +**When to Use**: Our commentary on when you should considering using this retrieval method. + +**Description**: Description of what this retrieval algorithm is doing. + +| Name | Index Type | Uses an LLM | When to Use | Description | +|---------------------------|------------------------------|---------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| [Vectorstore](https://api.python.langchain.com/en/latest/vectorstores/langchain_core.vectorstores.VectorStoreRetriever.html#langchain_core.vectorstores.VectorStoreRetriever) | Vectorstore | No | If you are just getting started and looking for something quick and easy. | This is the simplest method and the one that is easiest to get started with. It involves creating embeddings for each piece of text. | +| [ParentDocument](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.parent_document_retriever.ParentDocumentRetriever.html#langchain.retrievers.parent_document_retriever.ParentDocumentRetriever) | Vectorstore + Document Store | No | If your pages have lots of smaller pieces of distinct information that are best indexed by themselves, but best retrieved all together. | This involves indexing multiple chunks for each document. Then you find the chunks that are most similar in embedding space, but you retrieve the whole parent document and return that (rather than individual chunks). | +| [Multi Vector](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.multi_vector.MultiVectorRetriever.html#langchain.retrievers.multi_vector.MultiVectorRetriever) | Vectorstore + Document Store | Sometimes during indexing | If you are able to extract information from documents that you think is more relevant to index than the text itself. | This involves creating multiple vectors for each document. Each vector could be created in a myriad of ways - examples include summaries of the text and hypothetical questions. | +| [Self Query](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.self_query.base.SelfQueryRetriever.html#langchain.retrievers.self_query.base.SelfQueryRetriever) | Vectorstore | Yes | If users are asking questions that are better answered by fetching documents based on metadata rather than similarity with the text. | This uses an LLM to transform user input into two things: (1) a string to look up semantically, (2) a metadata filer to go along with it. This is useful because oftentimes questions are about the METADATA of documents (not the content itself). | +| [Contextual Compression](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.contextual_compression.ContextualCompressionRetriever.html#langchain.retrievers.contextual_compression.ContextualCompressionRetriever) | Any | Sometimes | If you are finding that your retrieved documents contain too much irrelevant information and are distracting the LLM. | This puts a post-processing step on top of another retriever and extracts only the most relevant information from retrieved documents. This can be done with embeddings or an LLM. | +| [Time-Weighted Vectorstore](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.time_weighted_retriever.TimeWeightedVectorStoreRetriever.html#langchain.retrievers.time_weighted_retriever.TimeWeightedVectorStoreRetriever) | Vectorstore | No | If you have timestamps associated with your documents, and you want to retrieve the most recent ones | This fetches documents based on a combination of semantic similarity (as in normal vector retrieval) and recency (looking at timestamps of indexed documents) | +| [Multi-Query Retriever](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.multi_query.MultiQueryRetriever.html#langchain.retrievers.multi_query.MultiQueryRetriever) | Any | Yes | If users are asking questions that are complex and require multiple pieces of distinct information to respond | This uses an LLM to generate multiple queries from the original one. This is useful when the original query needs pieces of information about multiple topics to be properly answered. By generating multiple queries, we can then fetch documents for each of them. | +| [Ensemble](https://api.python.langchain.com/en/latest/retrievers/langchain.retrievers.ensemble.EnsembleRetriever.html#langchain.retrievers.ensemble.EnsembleRetriever) | Any | No | If you have multiple retrieval methods and want to try combining them. | This fetches documents from multiple retrievers and then combines them. | + +### Tools +Tools are interfaces that an agent, chain, or LLM can use to interact with the world. +They combine a few things: + +1.

Whether the result of a tool should be returned directly to the user + +It is useful to have all this information because this information can be used to build action-taking systems! The name, description, and JSON schema can be used to prompt the LLM so it knows how to specify what action to take, and then the function to call is equivalent to taking that action. + +The simpler the input to a tool is, the easier it is for an LLM to be able to use it. +Many agents will only work with tools that have a single string input. + +Importantly, the name, description, and JSON schema (if used) are all used in the prompt. Therefore, it is really important that they are clear and describe exactly how the tool should be used. You may need to change the default name, description, or JSON schema if the LLM is not understanding how to use the tool. + + +### Toolkits + +Toolkits are collections of tools that are designed to be used together for specific tasks. They have convenient loading methods. + +All Toolkits expose a `get_tools` method which returns a list of tools. +You can therefore do: + +```python +# Initialize a toolkit +toolkit = ExampleTookit(...) + +# Get list of tools +tools = toolkit.get_tools() +``` + +### Agents + +By themselves, language models can't take actions - they just output text. +A big use case for LangChain is creating **agents**. +Agents are systems that use an LLM as a reasoning enginer to determine which actions to take and what the inputs to those actions should be. +The results of those actions can then be fed back into the agent and it determine whether more actions are needed, or whether it is okay to finish. + +[LangGraph](https://github.com/langchain-ai/langgraph) is an extension of LangChain specifically aimed at creating highly controllable and customizable agents. +Please check out that documentation for a more in depth overview of agent concepts. + +There is a legacy agent concept in LangChain that we are moving towards deprecating: `AgentExecutor`. +AgentExecutor was essentially a runtime for agents. +It was a great place to get started, however, it was not flexible enough as you started to have more customized agents. +In order to solve that we built LangGraph to be this flexible, highly-controllable runtime. + +If you are still using AgentExecutor, do not fear: we still have a guide on [how to use AgentExecutor](/docs/how_to/agent_executor). +It is recommended, however, that you start to transition to LangGraph. +In order to assist in this we have put together a [transition guide on how to do so](/docs/how_to/migrate_agent) diff --git a/docs/docs/expression_language/cookbook/code_writing.ipynb b/docs/docs/expression_language/cookbook/code_writing.ipynb deleted file mode 100644 index 731cba6f56d..00000000000 --- a/docs/docs/expression_language/cookbook/code_writing.ipynb +++ /dev/null @@ -1,139 +0,0 @@ -{ - "cells": [ - { - "cell_type": "raw", - "id": "1e997ab7", - "metadata": {}, - "source": [ - "---\n", - "sidebar_class_name: hidden\n", - "---" - ] - }, - { - "cell_type": "markdown", - "id": "f09fd305", - "metadata": {}, - "source": [ - "# Code writing\n", - "\n", - "Example of how to use LCEL to write Python code." - ] - }, - { - "cell_type": "code", - "execution_count": null, - "id": "0653c7c7", - "metadata": {}, - "outputs": [], - "source": [ - "%pip install --upgrade --quiet langchain-core langchain-experimental langchain-openai" - ] - }, - { - "cell_type": "code", - "execution_count": 1, - "id": "bd7c259a", - "metadata": {}, - "outputs": [], - "source": [ - "from langchain_core.output_parsers import StrOutputParser\n", - "from langchain_core.prompts import (\n", - " ChatPromptTemplate,\n", - ")\n", - "from langchain_experimental.utilities import PythonREPL\n", - "from langchain_openai import ChatOpenAI" - ] - }, - { - "cell_type": "code", - "execution_count": 12, - "id": "73795d2d", - "metadata": {}, - "outputs": [], - "source": [ - "template = \"\"\"Write some python code to solve the user's problem. \n", - "\n", - "Return only python code in Markdown format, e.g.:\n", - "\n", - "```python\n", - "....\n", - "```\"\"\"\n", - "prompt = ChatPromptTemplate.from_messages([(\"system\", template), (\"human\", \"{input}\")])\n", - "\n", - "model = ChatOpenAI()" - ] - }, - { - "cell_type": "code", - "execution_count": 13, - "id": "42859e8a", - "metadata": {}, - "outputs": [], - "source": [ - "def _sanitize_output(text: str):\n", - " _, after = text.split(\"```python\")\n", - " return after.split(\"```\")[0]" - ] - }, - { - "cell_type": "code", - "execution_count": 14, - "id": "5ded1a86", - "metadata": {}, - "outputs": [], - "source": [ - "chain = prompt | model | StrOutputParser() | _sanitize_output | PythonREPL().run" - ] - }, - { - "cell_type": "code", - "execution_count": 15, - "id": "208c2b75", - "metadata": {}, - "outputs": [ - { - "name": "stderr", - "output_type": "stream", - "text": [ - "Python REPL can execute arbitrary code.

The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\\n\\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\\n\\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\\n\\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\\n\\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework. With proper implementation and continuous improvement, organizations can leverage Scrum to drive innovation, efficiency, and project success.'" - ] - }, - "execution_count": 12, - "metadata": {}, - "output_type": "execute_result" - } - ], - "source": [ - "chain.invoke({\"input\": \"scrum\"})" - ] - } - ], - "metadata": { - "kernelspec": { - "display_name": "poetry-venv", - "language": "python", - "name": "poetry-venv" - }, - "language_info": { - "codemirror_mode": { - "name": "ipython", - "version": 3 - }, - "file_extension": ".py", - "mimetype": "text/x-python", - "name": "python", - "nbconvert_exporter": "python", - "pygments_lexer": "ipython3", - "version": "3.9.1" - } - }, - "nbformat": 4, - "nbformat_minor": 5 -} diff --git a/docs/docs/expression_language/cookbook/prompt_llm_parser.ipynb b/docs/docs/expression_language/cookbook/prompt_llm_parser.ipynb deleted file mode 100644 index 83de75f1818..00000000000 --- a/docs/docs/expression_language/cookbook/prompt_llm_parser.ipynb +++ /dev/null @@ -1,436 +0,0 @@ -{ - "cells": [ - { - "cell_type": "raw", - "id": "abf7263d-3a62-4016-b5d5-b157f92f2070", - "metadata": {}, - "source": [ - "---\n", - "sidebar_position: 0\n", - "title: Prompt + LLM\n", - "---\n" - ] - }, - { - "cell_type": "markdown", - "id": "9a434f2b-9405-468c-9dfd-254d456b57a6", - "metadata": {}, - "source": [ - "The most common and valuable composition is taking:\n", - "\n", - "``PromptTemplate`` / ``ChatPromptTemplate`` -> ``LLM`` / ``ChatModel`` -> ``OutputParser``\n", - "\n", - "Almost any other chains you build will use this building block." - ] - }, - { - "cell_type": "markdown", - "id": "93aa2c87", - "metadata": {}, - "source": [ - "## PromptTemplate + LLM\n", - "\n", - "The simplest composition is just combining a prompt and model to create a chain that takes user input, adds it to a prompt, passes it to a model, and returns the raw model output.\n", - "\n", - "Note, you can mix and match PromptTemplate/ChatPromptTemplates and LLMs/ChatModels as you like here." - ] - }, - { - "cell_type": "raw", - "id": "ef79a54b", - "metadata": {}, - "source": [ - "%pip install --upgrade --quiet langchain langchain-openai" - ] - }, - { - "cell_type": "code", - "execution_count": 1, - "id": "466b65b3", - "metadata": {}, - "outputs": [], - "source": [ - "from langchain_core.prompts import ChatPromptTemplate\n", - "from langchain_openai import ChatOpenAI\n", - "\n", - "prompt = ChatPromptTemplate.from_template(\"tell me a joke about {foo}\")\n", - "model = ChatOpenAI()\n", - "chain = prompt | model" - ] - }, - { - "cell_type": "code", - "execution_count": 2, - "id": "e3d0a6cd", - "metadata": {}, - "outputs": [ - { - "data": { - "text/plain": [ - "AIMessage(content=\"Why don't bears wear shoes?\\n\\nBecause they have bear feet!\", additional_kwargs={}, example=False)" - ] - }, - "execution_count": 2, - "metadata": {}, - "output_type": "execute_result" - } - ], - "source": [ - "chain.invoke({\"foo\": \"bears\"})" - ] - }, - { - "cell_type": "markdown", - "id": "7eb9ef50", - "metadata": {}, - "source": [ - "Often times we want to attach kwargs that'll be passed to each model call.

The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of individuals who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.\n", - "\n", - "Page: List of presidents of the United States by age\n", - "Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to January 25, 2024.\n", - "\n", - "Page: List of vice presidents of the United States\n", - "Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation from recurring. The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vice president is the first person in the presidential line of succession—that is, they assume the presidency if the president dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.\n", - "The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.\n", - "\n", - "Page: List of presidents of the United States by net worth\n", - "Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington. \t \n", - "Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.\n", - "\n", - "Page: List of presidents of the United States by home state\n", - "Summary: These lists give the states of primary affiliation and of birth for each president of the United States.\u001b[0m\u001b[32;1m\u001b[1;3m\n", - "Invoking: `Wikipedia` with `Joe Biden`\n", - "\n", - "\n", - "\u001b[0m\u001b[36;1m\u001b[1;3mPage: Joe Biden\n", - "Summary: Joseph Robinette Biden Jr. ( BY-dən; born November 20, 1942) is an American politician who is the 46th and current president of the United States.

He graduated from the University of Delaware before earning his law degree from Syracuse University. He was elected to the New Castle County Council in 1970 and to the U.S. Senate in 1972. As a senator, Biden drafted and led the effort to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act. He also oversaw six U.S. Supreme Court confirmation hearings, including the contentious hearings for Robert Bork and Clarence Thomas. Biden ran unsuccessfully for the Democratic presidential nomination in 1988 and 2008. In 2008, Obama chose Biden as his running mate, and he was a close counselor to Obama during his two terms as vice president. In the 2020 presidential election, Biden and his running mate, Kamala Harris, defeated incumbents Donald Trump and Mike Pence. He became the oldest president in U.S. history, and the first to have a female vice president.\n", - "As president, Biden signed the American Rescue Plan Act in response to the COVID-19 pandemic and subsequent recession. He signed bipartisan bills on infrastructure and manufacturing. He proposed the Build Back Better Act, which failed in Congress, but aspects of which were incorporated into the Inflation Reduction Act that he signed into law in 2022. Biden appointed Ketanji Brown Jackson to the Supreme Court. He worked with congressional Republicans to resolve the 2023 United States debt-ceiling crisis by negotiating a deal to raise the debt ceiling. In foreign policy, Biden restored America's membership in the Paris Agreement. He oversaw the complete withdrawal of U.S. troops from Afghanistan that ended the war in Afghanistan, during which the Afghan government collapsed and the Taliban seized control. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia and authorizing civilian and military aid to Ukraine. During the Israel–Hamas war, Biden announced military support for Israel, and condemned the actions of Hamas and other Palestinian militants as terrorism. In April 2023, Biden announced his candidacy for the Democratic nomination in the 2024 presidential election.\n", - "\n", - "Page: Presidency of Joe Biden\n", - "Summary: Joe Biden's tenure as the 46th president of the United States began with his inauguration on January 20, 2021. Biden, a Democrat from Delaware who previously served as vice president for two terms under president Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Biden won the presidency with a popular vote of over 81 million, the highest number of votes cast for a single United States presidential candidate. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. The administration's economic policies, known as \"Bidenomics\", were inspired and designed by Trickle-up economics. Described as growing the economy from the middle out and bottom up and growing the middle class. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding health care for US veterans, the Bipartisan Safer Communities Act and the Electoral Count Reform and Presidential Transition Improvement Act. In late 2022, Biden signed the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage in the United States. In response to the debt-ceiling crisis of 2023, Biden negotiated and signed the Fiscal Responsibility Act of 2023, which restrains federal spending for fiscal years 2024 and 2025, implements minor changes to SNAP and TANF, includes energy permitting reform, claws back some IRS funding and unspent money for COVID-19, and suspends the debt ceiling to January 1, 2025. Biden established the American Climate Corps and created the first ever White House Office of Gun Violence Prevention. On September 26, 2023, Joe Biden visited a United Auto Workers picket line during the 2023 United Auto Workers strike, making him the first US president to visit one.\n", - "The foreign policy goal of the Biden administration is to restore the US to a \"position of trusted leadership\" among global democracies in order to address the challenges posed by Russia and China. In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined military, economic, and humanitarian aid. Biden also approved a raid which led to the death of Abu Ibrahim al-Hashimi al-Qurashi, the leader of the Islamic State, and approved a drone strike which killed Ayman Al Zawahiri, leader of Al-Qaeda. Biden signed and created AUKUS, an international security alliance, together with Australia and the United Kingdom. Biden called for the expansion of NATO with the addition of Finland and Sweden, and rallied NATO allies in support of Ukraine. During the 2023 Israel–Hamas war, Biden condemned Hamas and other Palestinian militants as terrorism and announced American military support for Israel; Biden also showed his support and sympathy towards Palestinians affected by the war, sent humanitarian aid, and brokered a four-day temporary pause and hostage exchange.\n", - "\n", - "Page: Family of Joe Biden\n", - "Summary: Joe Biden, the 46th and current president of the United States, has family members who are prominent in law, education, activism and politics.

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.\n", - "The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies. New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.\n", - "Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.\n", - "On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning it the nickname \"The First State\".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealing to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.\n", - "\n", - "Page: Delaware City, Delaware\n", - "Summary: Delaware City is a city in New Castle County, Delaware, United States.

From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.\n", - "The river has been recognized by the National Wildlife Federation as one of the country's Great Waters and has been called the \"Lifeblood of the Northeast\" by American Rivers. Its watershed drains an area of 13,539 square miles (35,070 km2) and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct.\n", - "The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.\n", - "Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor, who defended the colony during the First Anglo-Powhatan War.\n", - "\n", - "Page: University of Delaware\n", - "Summary: The University of Delaware (colloquially known as UD or Delaware) is a privately governed, state-assisted land-grant research university located in Newark, Delaware.

The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of individuals who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.\n", - "\n", - "Page: List of presidents of the United States by age\n", - "Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to January 25, 2024.\n", - "\n", - "Page: List of vice presidents of the United States\n", - "Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation from recurring. The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vice president is the first person in the presidential line of succession—that is, they assume the presidency if the president dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.\n", - "The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.\n", - "\n", - "Page: List of presidents of the United States by net worth\n", - "Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington. \t \n", - "Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.\n", - "\n", - "Page: List of presidents of the United States by home state\n", - "Summary: These lists give the states of primary affiliation and of birth for each president of the United States.\u001b[0m\u001b[32;1m\u001b[1;3m\n", - "Invoking: `Wikipedia` with `Joe Biden`\n", - "\n", - "\n", - "\u001b[0m\u001b[36;1m\u001b[1;3mPage: Joe Biden\n", - "Summary: Joseph Robinette Biden Jr. ( BY-dən; born November 20, 1942) is an American politician who is the 46th and current president of the United States.

He graduated from the University of Delaware before earning his law degree from Syracuse University. He was elected to the New Castle County Council in 1970 and to the U.S. Senate in 1972. As a senator, Biden drafted and led the effort to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act. He also oversaw six U.S. Supreme Court confirmation hearings, including the contentious hearings for Robert Bork and Clarence Thomas. Biden ran unsuccessfully for the Democratic presidential nomination in 1988 and 2008. In 2008, Obama chose Biden as his running mate, and he was a close counselor to Obama during his two terms as vice president. In the 2020 presidential election, Biden and his running mate, Kamala Harris, defeated incumbents Donald Trump and Mike Pence.

In foreign policy, Biden restored America's membership in the Paris Agreement. He oversaw the complete withdrawal of U.S. troops from Afghanistan that ended the war in Afghanistan, during which the Afghan government collapsed and the Taliban seized control. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia and authorizing civilian and military aid to Ukraine.

Biden, a Democrat from Delaware who previously served as vice president for two terms under president Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Biden won the presidency with a popular vote of over 81 million, the highest number of votes cast for a single United States presidential candidate. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. The administration's economic policies, known as \"Bidenomics\", were inspired and designed by Trickle-up economics. Described as growing the economy from the middle out and bottom up and growing the middle class. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding health care for US veterans, the Bipartisan Safer Communities Act and the Electoral Count Reform and Presidential Transition Improvement Act. In late 2022, Biden signed the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage in the United States. In response to the debt-ceiling crisis of 2023, Biden negotiated and signed the Fiscal Responsibility Act of 2023, which restrains federal spending for fiscal years 2024 and 2025, implements minor changes to SNAP and TANF, includes energy permitting reform, claws back some IRS funding and unspent money for COVID-19, and suspends the debt ceiling to January 1, 2025.

On September 26, 2023, Joe Biden visited a United Auto Workers picket line during the 2023 United Auto Workers strike, making him the first US president to visit one.\n", - "The foreign policy goal of the Biden administration is to restore the US to a \"position of trusted leadership\" among global democracies in order to address the challenges posed by Russia and China. In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined military, economic, and humanitarian aid. Biden also approved a raid which led to the death of Abu Ibrahim al-Hashimi al-Qurashi, the leader of the Islamic State, and approved a drone strike which killed Ayman Al Zawahiri, leader of Al-Qaeda. Biden signed and created AUKUS, an international security alliance, together with Australia and the United Kingdom. Biden called for the expansion of NATO with the addition of Finland and Sweden, and rallied NATO allies in support of Ukraine. During the 2023 Israel–Hamas war, Biden condemned Hamas and other Palestinian militants as terrorism and announced American military support for Israel; Biden also showed his support and sympathy towards Palestinians affected by the war, sent humanitarian aid, and brokered a four-day temporary pause and hostage exchange.\n", - "\n", - "Page: Family of Joe Biden\n", - "Summary: Joe Biden, the 46th and current president of the United States, has family members who are prominent in law, education, activism and politics.

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.\n", - "The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies. New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.\n", - "Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.\n", - "On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning it the nickname \"The First State\".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealing to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.\n", - "\n", - "Page: Delaware City, Delaware\n", - "Summary: Delaware City is a city in New Castle County, Delaware, United States.

From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.\n", - "The river has been recognized by the National Wildlife Federation as one of the country's Great Waters and has been called the \"Lifeblood of the Northeast\" by American Rivers. Its watershed drains an area of 13,539 square miles (35,070 km2) and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct.\n", - "The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.\n", - "Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor, who defended the colony during the First Anglo-Powhatan War.\n", - "\n", - "Page: University of Delaware\n", - "Summary: The University of Delaware (colloquially known as UD or Delaware) is a privately governed, state-assisted land-grant research university located in Newark, Delaware.

To highlight a few of the reasons you might want to use LCEL: - -[**First-class streaming support**](/docs/expression_language/streaming) -When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. - -[**Async support**](/docs/expression_language/interface) -Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langserve) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server. - -[**Optimized parallel execution**](/docs/expression_language/primitives/parallel) -Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency. - -[**Retries and fallbacks**](/docs/guides/productionization/fallbacks) -Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost. - -[**Access intermediate results**](/docs/expression_language/interface#async-stream-events-beta) -For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced.

-# Quickstart - -In this quickstart we'll show you how to: -- Get setup with LangChain, LangSmith and LangServe -- Use the most basic and common components of LangChain: prompt templates, models, and output parsers -- Use LangChain Expression Language, the protocol that LangChain is built on and which facilitates component chaining -- Build a simple application with LangChain -- Trace your application with LangSmith -- Serve your application with LangServe - -That's a fair amount to cover! Let's dive in. - -## Setup - -### Jupyter Notebook - -This guide (and most of the other guides in the documentation) uses [Jupyter notebooks](https://jupyter.org/) and assumes the reader is as well. Jupyter notebooks are perfect for learning how to work with LLM systems because oftentimes things can go wrong (unexpected output, API down, etc) and going through guides in an interactive environment is a great way to better understand them. - -You do not NEED to go through the guide in a Jupyter Notebook, but it is recommended. See [here](https://jupyter.org/install) for instructions on how to install. - -### Installation - -To install LangChain run: - -import Tabs from '@theme/Tabs'; -import TabItem from '@theme/TabItem'; -import CodeBlock from "@theme/CodeBlock"; - - - - pip install langchain - - - conda install langchain -c conda-forge - - - - -For more details, see our [Installation guide](/docs/get_started/installation). - -### LangSmith - -Many of the applications you build with LangChain will contain multiple steps with multiple invocations of LLM calls. -As these applications get more and more complex, it becomes crucial to be able to inspect what exactly is going on inside your chain or agent. -The best way to do this is with [LangSmith](https://smith.langchain.com). - -Note that LangSmith is not needed, but it is helpful. -If you do want to use LangSmith, after you sign up at the link above, make sure to set your environment variables to start logging traces: - -```shell -export LANGCHAIN_TRACING_V2="true" -export LANGCHAIN_API_KEY="..." -``` - -## Building with LangChain - -LangChain enables building application that connect external sources of data and computation to LLMs. -In this quickstart, we will walk through a few different ways of doing that. -We will start with a simple LLM chain, which just relies on information in the prompt template to respond. -Next, we will build a retrieval chain, which fetches data from a separate database and passes that into the prompt template. -We will then add in chat history, to create a conversation retrieval chain. This allows you to interact in a chat manner with this LLM, so it remembers previous questions. -Finally, we will build an agent - which utilizes an LLM to determine whether or not it needs to fetch data to answer questions. -We will cover these at a high level, but there are lot of details to all of these! -We will link to relevant docs. - -## LLM Chain - -We'll show how to use models available via API, like OpenAI, and local open source models, using integrations like Ollama. - - - - -First we'll need to import the LangChain x OpenAI integration package. - -```shell -pip install langchain-openai -``` - -Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running: - -```shell -export OPENAI_API_KEY="..." -``` - -We can then initialize the model: - -```python -from langchain_openai import ChatOpenAI - -llm = ChatOpenAI() -``` - -If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the OpenAI LLM class: - -```python -from langchain_openai import ChatOpenAI - -llm = ChatOpenAI(api_key="...") -``` - - - - -[Ollama](https://ollama.ai/) allows you to run open-source large language models, such as Llama 2, locally. - -First, follow [these instructions](https://github.com/jmorganca/ollama) to set up and run a local Ollama instance: - -* [Download](https://ollama.ai/download) -* Fetch a model via `ollama pull llama2` - -Then, make sure the Ollama server is running. After that, you can do: -```python -from langchain_community.llms import Ollama -llm = Ollama(model="llama2") -``` - - - - -First we'll need to import the LangChain x Anthropic package. - -```shell -pip install langchain-anthropic -``` - -Accessing the API requires an API key, which you can get by creating an account [here](https://claude.ai/login). Once we have a key we'll want to set it as an environment variable by running: - -```shell -export ANTHROPIC_API_KEY="..." -``` - -We can then initialize the model: - -```python -from langchain_anthropic import ChatAnthropic - -llm = ChatAnthropic(model="claude-3-sonnet-20240229", temperature=0.2, max_tokens=1024) -``` - -If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the Anthropic Chat Model class: - -```python -llm = ChatAnthropic(api_key="...") -``` - - - - -First we'll need to import the Cohere SDK package. - -```shell -pip install langchain-cohere -``` - -Accessing the API requires an API key, which you can get by creating an account and heading [here](https://dashboard.cohere.com/api-keys). Once we have a key we'll want to set it as an environment variable by running: - -```shell -export COHERE_API_KEY="..." -``` - -We can then initialize the model: - -```python -from langchain_cohere import ChatCohere - -llm = ChatCohere() -``` - -If you'd prefer not to set an environment variable you can pass the key in directly via the `cohere_api_key` named parameter when initiating the Cohere LLM class: - -```python -from langchain_cohere import ChatCohere - -llm = ChatCohere(cohere_api_key="...") -``` - - - - -Once you've installed and initialized the LLM of your choice, we can try using it! -Let's ask it what LangSmith is - this is something that wasn't present in the training data so it shouldn't have a very good response. - -```python -llm.invoke("how can langsmith help with testing?") -``` - -We can also guide its response with a prompt template. -Prompt templates convert raw user input to better input to the LLM. - -```python -from langchain_core.prompts import ChatPromptTemplate -prompt = ChatPromptTemplate.from_messages([ - ("system", "You are a world class technical documentation writer."), - ("user", "{input}") -]) -``` - -We can now combine these into a simple LLM chain: - -```python -chain = prompt | llm -``` - -We can now invoke it and ask the same question. It still won't know the answer, but it should respond in a more proper tone for a technical writer! - -```python -chain.invoke({"input": "how can langsmith help with testing?"}) -``` - -The output of a ChatModel (and therefore, of this chain) is a message. However, it's often much more convenient to work with strings. Let's add a simple output parser to convert the chat message to a string. - -```python -from langchain_core.output_parsers import StrOutputParser - -output_parser = StrOutputParser() -``` - -We can now add this to the previous chain: - -```python -chain = prompt | llm | output_parser -``` - -We can now invoke it and ask the same question. The answer will now be a string (rather than a ChatMessage). - -```python -chain.invoke({"input": "how can langsmith help with testing?"}) -``` - -### Diving Deeper - -We've now successfully set up a basic LLM chain. We only touched on the basics of prompts, models, and output parsers - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/model_io). - - -## Retrieval Chain - -To properly answer the original question ("how can langsmith help with testing?"), we need to provide additional context to the LLM. -We can do this via *retrieval*. -Retrieval is useful when you have **too much data** to pass to the LLM directly. -You can then use a retriever to fetch only the most relevant pieces and pass those in. - -In this process, we will look up relevant documents from a *Retriever* and then pass them into the prompt. -A Retriever can be backed by anything - a SQL table, the internet, etc - but in this instance we will populate a vector store and use that as a retriever. For more information on vectorstores, see [this documentation](/docs/modules/data_connection/vectorstores). - -First, we need to load the data that we want to index. To do this, we will use the WebBaseLoader. This requires installing [BeautifulSoup](https://beautiful-soup-4.readthedocs.io/en/latest/): - -```shell -pip install beautifulsoup4 -``` - -After that, we can import and use WebBaseLoader. - - -```python -from langchain_community.document_loaders import WebBaseLoader -loader = WebBaseLoader("https://docs.smith.langchain.com/user_guide") - -docs = loader.load() -``` - -Next, we need to index it into a vectorstore. This requires a few components, namely an [embedding model](/docs/modules/data_connection/text_embedding) and a [vectorstore](/docs/modules/data_connection/vectorstores). - -For embedding models, we once again provide examples for accessing via API or by running local models. - - - - -Make sure you have the `langchain_openai` package installed an the appropriate environment variables set (these are the same as needed for the LLM). - -```python -from langchain_openai import OpenAIEmbeddings - -embeddings = OpenAIEmbeddings() -``` - - - - -Make sure you have Ollama running (same set up as with the LLM). - -```python -from langchain_community.embeddings import OllamaEmbeddings - -embeddings = OllamaEmbeddings() -``` - - - -Make sure you have the `cohere` package installed and the appropriate environment variables set (these are the same as needed for the LLM). - -```python -from langchain_cohere.embeddings import CohereEmbeddings - -embeddings = CohereEmbeddings() -``` - - - - -Now, we can use this embedding model to ingest documents into a vectorstore. -We will use a simple local vectorstore, [FAISS](/docs/integrations/vectorstores/faiss), for simplicity's sake. - -First we need to install the required packages for that: - -```shell -pip install faiss-cpu -``` - -Then we can build our index: - -```python -from langchain_community.vectorstores import FAISS -from langchain_text_splitters import RecursiveCharacterTextSplitter - - -text_splitter = RecursiveCharacterTextSplitter() -documents = text_splitter.split_documents(docs) -vector = FAISS.from_documents(documents, embeddings) -``` - -Now that we have this data indexed in a vectorstore, we will create a retrieval chain. -This chain will take an incoming question, look up relevant documents, then pass those documents along with the original question into an LLM and ask it to answer the original question. - -First, let's set up the chain that takes a question and the retrieved documents and generates an answer. - -```python -from langchain.chains.combine_documents import create_stuff_documents_chain - -prompt = ChatPromptTemplate.from_template("""Answer the following question based only on the provided context: - - -{context} - - -Question: {input}""") - -document_chain = create_stuff_documents_chain(llm, prompt) -``` - -If we wanted to, we could run this ourselves by passing in documents directly: - -```python -from langchain_core.documents import Document - -document_chain.invoke({ - "input": "how can langsmith help with testing?", - "context": [Document(page_content="langsmith can let you visualize test results")] -}) -``` - -However, we want the documents to first come from the retriever we just set up. -That way, we can use the retriever to dynamically select the most relevant documents and pass those in for a given question. - -```python -from langchain.chains import create_retrieval_chain - -retriever = vector.as_retriever() -retrieval_chain = create_retrieval_chain(retriever, document_chain) -``` - -We can now invoke this chain. This returns a dictionary - the response from the LLM is in the `answer` key - -```python -response = retrieval_chain.invoke({"input": "how can langsmith help with testing?"}) -print(response["answer"]) - -# LangSmith offers several features that can help with testing:... -``` - -This answer should be much more accurate! - -### Diving Deeper - -We've now successfully set up a basic retrieval chain. We only touched on the basics of retrieval - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/data_connection). - -## Conversation Retrieval Chain - -The chain we've created so far can only answer single questions. One of the main types of LLM applications that people are building are chat bots. So how do we turn this chain into one that can answer follow up questions? - -We can still use the `create_retrieval_chain` function, but we need to change two things: - -1. The retrieval method should now not just work on the most recent input, but rather should take the whole history into account. -2. The final LLM chain should likewise take the whole history into account - -**Updating Retrieval** - -In order to update retrieval, we will create a new chain. This chain will take in the most recent input (`input`) and the conversation history (`chat_history`) and use an LLM to generate a search query. - -```python -from langchain.chains import create_history_aware_retriever -from langchain_core.prompts import MessagesPlaceholder - -# First we need a prompt that we can pass into an LLM to generate this search query - -prompt = ChatPromptTemplate.from_messages([ - MessagesPlaceholder(variable_name="chat_history"), - ("user", "{input}"), - ("user", "Given the above conversation, generate a search query to look up to get information relevant to the conversation") -]) -retriever_chain = create_history_aware_retriever(llm, retriever, prompt) -``` - -We can test this out by passing in an instance where the user asks a follow-up question. - -```python -from langchain_core.messages import HumanMessage, AIMessage - -chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] -retriever_chain.invoke({ - "chat_history": chat_history, - "input": "Tell me how" -}) -``` -You should see that this returns documents about testing in LangSmith. This is because the LLM generated a new query, combining the chat history with the follow-up question. - -Now that we have this new retriever, we can create a new chain to continue the conversation with these retrieved documents in mind. - -```python -prompt = ChatPromptTemplate.from_messages([ - ("system", "Answer the user's questions based on the below context:\n\n{context}"), - MessagesPlaceholder(variable_name="chat_history"), - ("user", "{input}"), -]) -document_chain = create_stuff_documents_chain(llm, prompt) - -retrieval_chain = create_retrieval_chain(retriever_chain, document_chain) -``` - -We can now test this out end-to-end: - -```python -chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] -retrieval_chain.invoke({ - "chat_history": chat_history, - "input": "Tell me how" -}) -``` -We can see that this gives a coherent answer - we've successfully turned our retrieval chain into a chatbot! - -## Agent - -We've so far created examples of chains - where each step is known ahead of time. -The final thing we will create is an agent - where the LLM decides what steps to take. - -**NOTE: for this example we will only show how to create an agent using OpenAI models, as local models are not reliable enough yet.** - -One of the first things to do when building an agent is to decide what tools it should have access to. -For this example, we will give the agent access to two tools: - -1. The retriever we just created. This will let it easily answer questions about LangSmith -2. A search tool. This will let it easily answer questions that require up-to-date information. - -First, let's set up a tool for the retriever we just created: - -```python -from langchain.tools.retriever import create_retriever_tool - -retriever_tool = create_retriever_tool( - retriever, - "langsmith_search", - "Search for information about LangSmith. For any questions about LangSmith, you must use this tool!", -) -``` - - -The search tool that we will use is [Tavily](/docs/integrations/retrievers/tavily). This will require an API key (they have generous free tier). After creating it on their platform, you need to set it as an environment variable: - -```shell -export TAVILY_API_KEY=... -``` -If you do not want to set up an API key, you can skip creating this tool. - -```python -from langchain_community.tools.tavily_search import TavilySearchResults - -search = TavilySearchResults() -``` - -We can now create a list of the tools we want to work with: - -```python -tools = [retriever_tool, search] -``` - -Now that we have the tools, we can create an agent to use them. We will go over this pretty quickly - for a deeper dive into what exactly is going on, check out the [Agent's Getting Started documentation](/docs/modules/agents) - -Install langchain hub first -```bash -pip install langchainhub -``` -Install the langchain-openai package -To interact with OpenAI we need to use langchain-openai which connects with OpenAI SDK[https://github.com/langchain-ai/langchain/tree/master/libs/partners/openai]. -```bash -pip install langchain-openai -``` - -Now we can use it to get a predefined prompt - -```python -from langchain_openai import ChatOpenAI -from langchain import hub -from langchain.agents import create_openai_functions_agent -from langchain.agents import AgentExecutor - -# Get the prompt to use - you can modify this! -prompt = hub.pull("hwchase17/openai-functions-agent") - -# You need to set OPENAI_API_KEY environment variable or pass it as argument `api_key`. -llm = ChatOpenAI(model="gpt-3.5-turbo", temperature=0) -agent = create_openai_functions_agent(llm, tools, prompt) -agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True) -``` - -We can now invoke the agent and see how it responds! We can ask it questions about LangSmith: - -```python -agent_executor.invoke({"input": "how can langsmith help with testing?"}) -``` - -We can ask it about the weather: - -```python -agent_executor.invoke({"input": "what is the weather in SF?"}) -``` - -We can have conversations with it: - -```python -chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] -agent_executor.invoke({ - "chat_history": chat_history, - "input": "Tell me how" -}) -``` - -### Diving Deeper - -We've now successfully set up a basic agent. We only touched on the basics of agents - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/agents). - - -## Serving with LangServe - -Now that we've built an application, we need to serve it. That's where LangServe comes in. -LangServe helps developers deploy LangChain chains as a REST API. You do not need to use LangServe to use LangChain, but in this guide we'll show how you can deploy your app with LangServe. - -While the first part of this guide was intended to be run in a Jupyter Notebook, we will now move out of that. We will be creating a Python file and then interacting with it from the command line. - -Install with: -```bash -pip install "langserve[all]" -``` - -### Server - -To create a server for our application we'll make a `serve.py` file. This will contain our logic for serving our application. It consists of three things: -1. The definition of our chain that we just built above -2. Our FastAPI app -3. A definition of a route from which to serve the chain, which is done with `langserve.add_routes` - -```python -#!/usr/bin/env python -from typing import List - -from fastapi import FastAPI -from langchain_core.prompts import ChatPromptTemplate -from langchain_openai import ChatOpenAI -from langchain_community.document_loaders import WebBaseLoader -from langchain_openai import OpenAIEmbeddings -from langchain_community.vectorstores import FAISS -from langchain_text_splitters import RecursiveCharacterTextSplitter -from langchain.tools.retriever import create_retriever_tool -from langchain_community.tools.tavily_search import TavilySearchResults -from langchain import hub -from langchain.agents import create_openai_functions_agent -from langchain.agents import AgentExecutor -from langchain.pydantic_v1 import BaseModel, Field -from langchain_core.messages import BaseMessage -from langserve import add_routes - -# 1.

-In today's fast-paced technological landscape, the use of Large Language Models (LLMs) is rapidly expanding. As a result, it is crucial for developers to understand how to effectively deploy these models in production environments. LLM interfaces typically fall into two categories: - -- **Case 1: Utilizing External LLM Providers (OpenAI, Anthropic, etc.)** - In this scenario, most of the computational burden is handled by the LLM providers, while LangChain simplifies the implementation of business logic around these services. This approach includes features such as prompt templating, chat message generation, caching, vector embedding database creation, preprocessing, etc. - -- **Case 2: Self-hosted Open-Source Models** - Alternatively, developers can opt to use smaller, yet comparably capable, self-hosted open-source LLM models. This approach can significantly decrease costs, latency, and privacy concerns associated with transferring data to external LLM providers. - -Regardless of the framework that forms the backbone of your product, deploying LLM applications comes with its own set of challenges. It's vital to understand the trade-offs and key considerations when evaluating serving frameworks. - -## Outline - -This guide aims to provide a comprehensive overview of the requirements for deploying LLMs in a production setting, focusing on: - -- **Designing a Robust LLM Application Service** -- **Maintaining Cost-Efficiency** -- **Ensuring Rapid Iteration** - -Understanding these components is crucial when assessing serving systems. LangChain integrates with several open-source projects designed to tackle these issues, providing a robust framework for productionizing your LLM applications. Some notable frameworks include: - -- [Ray Serve](/docs/integrations/providers/ray_serve) -- [BentoML](https://github.com/bentoml/BentoML) -- [OpenLLM](/docs/integrations/providers/openllm) -- [Modal](/docs/integrations/providers/modal) -- [Jina](/docs/integrations/providers/jina) - -These links will provide further information on each ecosystem, assisting you in finding the best fit for your LLM deployment needs. - -## Designing a Robust LLM Application Service - -When deploying an LLM service in production, it's imperative to provide a seamless user experience free from outages. Achieving 24/7 service availability involves creating and maintaining several sub-systems surrounding your application. - -### Monitoring - -Monitoring forms an integral part of any system running in a production environment. In the context of LLMs, it is essential to monitor both performance and quality metrics. - -**Performance Metrics:** These metrics provide insights into the efficiency and capacity of your model. Here are some key examples: - -- Query per second (QPS): This measures the number of queries your model processes in a second, offering insights into its utilization. -- Latency: This metric quantifies the delay from when your client sends a request to when they receive a response. -- Tokens Per Second (TPS): This represents the number of tokens your model can generate in a second. - -**Quality Metrics:** These metrics are typically customized according to the business use-case. For instance, how does the output of your system compare to a baseline, such as a previous version? Although these metrics can be calculated offline, you need to log the necessary data to use them later. - -### Fault tolerance - -Your application may encounter errors such as exceptions in your model inference or business logic code, causing failures and disrupting traffic. Other potential issues could arise from the machine running your application, such as unexpected hardware breakdowns or loss of spot-instances during high-demand periods. One way to mitigate these risks is by increasing redundancy through replica scaling and implementing recovery mechanisms for failed replicas. However, model replicas aren't the only potential points of failure. It's essential to build resilience against various failures that could occur at any point in your stack. - - -### Zero down time upgrade - -System upgrades are often necessary but can result in service disruptions if not handled correctly. One way to prevent downtime during upgrades is by implementing a smooth transition process from the old version to the new one. Ideally, the new version of your LLM service is deployed, and traffic gradually shifts from the old to the new version, maintaining a constant QPS throughout the process. - - -### Load balancing - -Load balancing, in simple terms, is a technique to distribute work evenly across multiple computers, servers, or other resources to optimize the utilization of the system, maximize throughput, minimize response time, and avoid overload of any single resource. Think of it as a traffic officer directing cars (requests) to different roads (servers) so that no single road becomes too congested. - -There are several strategies for load balancing. For example, one common method is the *Round Robin* strategy, where each request is sent to the next server in line, cycling back to the first when all servers have received a request. This works well when all servers are equally capable. However, if some servers are more powerful than others, you might use a *Weighted Round Robin* or *Least Connections* strategy, where more requests are sent to the more powerful servers, or to those currently handling the fewest active requests. Let's imagine you're running a LLM chain. If your application becomes popular, you could have hundreds or even thousands of users asking questions at the same time. If one server gets too busy (high load), the load balancer would direct new requests to another server that is less busy. This way, all your users get a timely response and the system remains stable. - - - -## Maintaining Cost-Efficiency and Scalability - -Deploying LLM services can be costly, especially when you're handling a large volume of user interactions. Charges by LLM providers are usually based on tokens used, making a chat system inference on these models potentially expensive. However, several strategies can help manage these costs without compromising the quality of the service. - - -### Self-hosting models - -Several smaller and open-source LLMs are emerging to tackle the issue of reliance on LLM providers. Self-hosting allows you to maintain similar quality to LLM provider models while managing costs. The challenge lies in building a reliable, high-performing LLM serving system on your own machines. - -### Resource Management and Auto-Scaling - -Computational logic within your application requires precise resource allocation. For instance, if part of your traffic is served by an OpenAI endpoint and another part by a self-hosted model, it's crucial to allocate suitable resources for each. Auto-scaling—adjusting resource allocation based on traffic—can significantly impact the cost of running your application. This strategy requires a balance between cost and responsiveness, ensuring neither resource over-provisioning nor compromised application responsiveness. - -### Utilizing Spot Instances - -On platforms like AWS, spot instances offer substantial cost savings, typically priced at about a third of on-demand instances. The trade-off is a higher crash rate, necessitating a robust fault-tolerance mechanism for effective use. - -### Independent Scaling - -When self-hosting your models, you should consider independent scaling. For example, if you have two translation models, one fine-tuned for French and another for Spanish, incoming requests might necessitate different scaling requirements for each. - -### Batching requests - -In the context of Large Language Models, batching requests can enhance efficiency by better utilizing your GPU resources. GPUs are inherently parallel processors, designed to handle multiple tasks simultaneously. If you send individual requests to the model, the GPU might not be fully utilized as it's only working on a single task at a time. On the other hand, by batching requests together, you're allowing the GPU to work on multiple tasks at once, maximizing its utilization and improving inference speed. This not only leads to cost savings but can also improve the overall latency of your LLM service. - - -In summary, managing costs while scaling your LLM services requires a strategic approach. Utilizing self-hosting models, managing resources effectively, employing auto-scaling, using spot instances, independently scaling models, and batching requests are key strategies to consider. Open-source libraries such as Ray Serve and BentoML are designed to deal with these complexities. - - - -## Ensuring Rapid Iteration - -The LLM landscape is evolving at an unprecedented pace, with new libraries and model architectures being introduced constantly. Consequently, it's crucial to avoid tying yourself to a solution specific to one particular framework. This is especially relevant in serving, where changes to your infrastructure can be time-consuming, expensive, and risky. Strive for infrastructure that is not locked into any specific machine learning library or framework, but instead offers a general-purpose, scalable serving layer. Here are some aspects where flexibility plays a key role: - -### Model composition - -Deploying systems like LangChain demands the ability to piece together different models and connect them via logic. Take the example of building a natural language input SQL query engine. Querying an LLM and obtaining the SQL command is only part of the system. You need to extract metadata from the connected database, construct a prompt for the LLM, run the SQL query on an engine, collect and feedback the response to the LLM as the query runs, and present the results to the user. This demonstrates the need to seamlessly integrate various complex components built in Python into a dynamic chain of logical blocks that can be served together. - -## Cloud providers - -Many hosted solutions are restricted to a single cloud provider, which can limit your options in today's multi-cloud world. Depending on where your other infrastructure components are built, you might prefer to stick with your chosen cloud provider. - - -## Infrastructure as Code (IaC) - -Rapid iteration also involves the ability to recreate your infrastructure quickly and reliably. This is where Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Kubernetes YAML files come into play. They allow you to define your infrastructure in code files, which can be version controlled and quickly deployed, enabling faster and more reliable iterations. - - -## CI/CD - -In a fast-paced environment, implementing CI/CD pipelines can significantly speed up the iteration process. They help automate the testing and deployment of your LLM applications, reducing the risk of errors and enabling faster feedback and iteration. diff --git a/docs/docs/guides/productionization/deployments/template_repos.mdx b/docs/docs/guides/productionization/deployments/template_repos.mdx deleted file mode 100644 index 4a8082864ee..00000000000 --- a/docs/docs/guides/productionization/deployments/template_repos.mdx +++ /dev/null @@ -1,7 +0,0 @@ -# LangChain Templates - -For more information on LangChain Templates, visit - -- [LangChain Templates Quickstart](https://github.com/langchain-ai/langchain/blob/master/templates/README.md) -- [LangChain Templates Index](https://github.com/langchain-ai/langchain/blob/master/templates/docs/INDEX.md) -- [Full List of Templates](https://github.com/langchain-ai/langchain/blob/master/templates/) \ No newline at end of file diff --git a/docs/docs/guides/productionization/evaluation/comparison/custom.ipynb b/docs/docs/guides/productionization/evaluation/comparison/custom.ipynb deleted file mode 100644 index 3b10f833e86..00000000000 --- a/docs/docs/guides/productionization/evaluation/comparison/custom.ipynb +++ /dev/null @@ -1,293 +0,0 @@ -{ - "cells": [ - { - "cell_type": "raw", - "id": "5046d96f-d578-4d5b-9a7e-43b28cafe61d", - "metadata": {}, - "source": [ - "---\n", - "sidebar_position: 2\n", - "title: Custom pairwise evaluator\n", - "---" - ] - }, - { - "cell_type": "markdown", - "id": "657d2c8c-54b4-42a3-9f02-bdefa0ed6728", - "metadata": {}, - "source": [ - "[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/langchain-ai/langchain/blob/master/docs/docs/guides/evaluation/comparison/custom.ipynb)\n", - "\n", - "You can make your own pairwise string evaluators by inheriting from `PairwiseStringEvaluator` class and overwriting the `_evaluate_string_pairs` method (and the `_aevaluate_string_pairs` method if you want to use the evaluator asynchronously).\n", - "\n", - "In this example, you will make a simple custom evaluator that just returns whether the first prediction has more whitespace tokenized 'words' than the second.\n", - "\n", - "You can check out the reference docs for the [PairwiseStringEvaluator interface](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.schema.PairwiseStringEvaluator.html#langchain.evaluation.schema.PairwiseStringEvaluator) for more info.\n" - ] - }, - { - "cell_type": "code", - "execution_count": 1, - "id": "93f3a653-d198-4291-973c-8d1adba338b2", - "metadata": { - "tags": [] - }, - "outputs": [], - "source": [ - "from typing import Any, Optional\n", - "\n", - "from langchain.evaluation import PairwiseStringEvaluator\n", - "\n", - "\n", - "class LengthComparisonPairwiseEvaluator(PairwiseStringEvaluator):\n", - " \"\"\"\n", - " Custom evaluator to compare two strings.\n", - " \"\"\"\n", - "\n", - " def _evaluate_string_pairs(\n", - " self,\n", - " *,\n", - " prediction: str,\n", - " prediction_b: str,\n", - " reference: Optional[str] = None,\n", - " input: Optional[str] = None,\n", - " **kwargs: Any,\n", - " ) -> dict:\n", - " score = int(len(prediction.split()) > len(prediction_b.split()))\n", - " return {\"score\": score}" - ] - }, - { - "cell_type": "code", - "execution_count": 2, - "id": "7d4a77c3-07a7-4076-8e7f-f9bca0d6c290", - "metadata": { - "tags": [] - }, - "outputs": [ - { - "data": { - "text/plain": [ - "{'score': 1}" - ] - }, - "execution_count": 2, - "metadata": {}, - "output_type": "execute_result" - } - ], - "source": [ - "evaluator = LengthComparisonPairwiseEvaluator()\n", - "\n", - "evaluator.evaluate_string_pairs(\n", - " prediction=\"The quick brown fox jumped over the lazy dog.\",\n", - " prediction_b=\"The quick brown fox jumped over the dog.\",\n", - ")" - ] - }, - { - "cell_type": "markdown", - "id": "d90f128f-6f49-42a1-b05a-3aea568ee03b", - "metadata": {}, - "source": [ - "## LLM-Based Example\n", - "\n", - "That example was simple to illustrate the API, but it wasn't very useful in practice.

One of the most critical components is ensuring that the outcomes produced by your models are reliable and useful across a broad array of inputs, and that they work well with your application's other software components. Ensuring reliability usually boils down to some combination of application design, testing & evaluation, and runtime checks. - -The guides in this section review the APIs and functionality LangChain provides to help you better evaluate your applications. Evaluation and testing are both critical when thinking about deploying LLM applications, since production environments require repeatable and useful outcomes. - -LangChain offers various types of evaluators to help you measure performance and integrity on diverse data, and we hope to encourage the community to create and share other useful evaluators so everyone can improve. These docs will introduce the evaluator types, how to use them, and provide some examples of their use in real-world scenarios. -These built-in evaluators all integrate smoothly with [LangSmith](/docs/langsmith), and allow you to create feedback loops that improve your application over time and prevent regressions. - -Each evaluator type in LangChain comes with ready-to-use implementations and an extensible API that allows for customization according to your unique requirements. Here are some of the types of evaluators we offer: - -- [String Evaluators](/docs/guides/productionization/evaluation/string/): These evaluators assess the predicted string for a given input, usually comparing it against a reference string. -- [Trajectory Evaluators](/docs/guides/productionization/evaluation/trajectory/): These are used to evaluate the entire trajectory of agent actions. -- [Comparison Evaluators](/docs/guides/productionization/evaluation/comparison/): These evaluators are designed to compare predictions from two runs on a common input. - -These evaluators can be used across various scenarios and can be applied to different chain and LLM implementations in the LangChain library. - -We also are working to share guides and cookbooks that demonstrate how to use these evaluators in real-world scenarios, such as: - -- [Chain Comparisons](/docs/guides/productionization/evaluation/examples/comparisons): This example uses a comparison evaluator to predict the preferred output. It reviews ways to measure confidence intervals to select statistically significant differences in aggregate preference scores across different models or prompts. - - -## LangSmith Evaluation - -LangSmith provides an integrated evaluation and tracing framework that allows you to check for regressions, compare systems, and easily identify and fix any sources of errors and performance issues. Check out the docs on [LangSmith Evaluation](https://docs.smith.langchain.com/evaluation) and additional [cookbooks](https://docs.smith.langchain.com/cookbook) for more detailed information on evaluating your applications. - -## LangChain benchmarks - -Your application quality is a function both of the LLM you choose and the prompting and data retrieval strategies you employ to provide model contexet.

-A string evaluator is a component within LangChain designed to assess the performance of a language model by comparing its generated outputs (predictions) to a reference string or an input. This comparison is a crucial step in the evaluation of language models, providing a measure of the accuracy or quality of the generated text. - -In practice, string evaluators are typically used to evaluate a predicted string against a given input, such as a question or a prompt. Often, a reference label or context string is provided to define what a correct or ideal response would look like. These evaluators can be customized to tailor the evaluation process to fit your application's specific requirements. - -To create a custom string evaluator, inherit from the `StringEvaluator` class and implement the `_evaluate_strings` method. If you require asynchronous support, also implement the `_aevaluate_strings` method. - -Here's a summary of the key attributes and methods associated with a string evaluator: - -- `evaluation_name`: Specifies the name of the evaluation. -- `requires_input`: Boolean attribute that indicates whether the evaluator requires an input string. If True, the evaluator will raise an error when the input isn't provided. If False, a warning will be logged if an input _is_ provided, indicating that it will not be considered in the evaluation. -- `requires_reference`: Boolean attribute specifying whether the evaluator requires a reference label. If True, the evaluator will raise an error when the reference isn't provided. If False, a warning will be logged if a reference _is_ provided, indicating that it will not be considered in the evaluation. - -String evaluators also implement the following methods: - -- `aevaluate_strings`: Asynchronously evaluates the output of the Chain or Language Model, with support for optional input and label. -- `evaluate_strings`: Synchronously evaluates the output of the Chain or Language Model, with support for optional input and label. - -The following sections provide detailed information on available string evaluator implementations as well as how to create a custom string evaluator. - -import DocCardList from "@theme/DocCardList"; - - diff --git a/docs/docs/guides/productionization/evaluation/string/json.ipynb b/docs/docs/guides/productionization/evaluation/string/json.ipynb deleted file mode 100644 index 37bd82cc929..00000000000 --- a/docs/docs/guides/productionization/evaluation/string/json.ipynb +++ /dev/null @@ -1,385 +0,0 @@ -{ - "cells": [ - { - "cell_type": "markdown", - "id": "465cfbef-5bba-4b3b-b02d-fe2eba39db17", - "metadata": {}, - "source": [ - "# JSON Evaluators\n", - "\n", - "Evaluating [extraction](/docs/use_cases/extraction) and function calling applications often comes down to validation that the LLM's string output can be parsed correctly and how it compares to a reference object.
