 # langchain
 
+## 0.2.0
+
+### Deleted
+
+As of release 0.2.0, `langchain` is required to be integration-agnostic. This means that code in `langchain`  should not by default instantiate any specific chat models, llms, embedding models, vectorstores etc; instead, the user will be required to specify those explicitly.
+
+The following functions and classes require an explicit LLM to be passed as an argument:
+
+- `langchain.agents.agent_toolkits.vectorstore.toolkit.VectorStoreToolkit`
+- `langchain.agents.agent_toolkits.vectorstore.toolkit.VectorStoreRouterToolkit`
+- `langchain.chains.openai_functions.get_openapi_chain`
+- `langchain.chains.router.MultiRetrievalQAChain.from_retrievers`
+- `langchain.indexes.VectorStoreIndexWrapper.query`
+- `langchain.indexes.VectorStoreIndexWrapper.query_with_sources`
+- `langchain.indexes.VectorStoreIndexWrapper.aquery_with_sources`
+- `langchain.chains.flare.FlareChain`
+
+The following classes now require passing an explicit Embedding model as an argument:
+
+- `langchain.indexes.VectostoreIndexCreator`
+
+The following code has been removed:
+
+- `langchain.natbot.NatBotChain.from_default` removed in favor of the `from_llm` class method.
+
+### Deprecated
+
+We have two main types of deprecations:
+
+1. Code that was moved from `langchain` into another package (e.g, `langchain-community`)
+
+If you try to import it from `langchain`, the import will keep on working, but will raise a deprecation warning. The warning will provide a replacement import statement.
+
+```python
+python -c "from langchain.document_loaders.markdown import UnstructuredMarkdownLoader"
+
+```
+
+```python
+LangChainDeprecationWarning: Importing UnstructuredMarkdownLoader from langchain.document_loaders is deprecated. Please replace deprecated imports:
+
+>> from langchain.document_loaders import UnstructuredMarkdownLoader
+
+with new imports of:
+
+>> from langchain_community.document_loaders import UnstructuredMarkdownLoader
+```
+
+We will continue supporting the imports in `langchain` until release 0.4 as long as the relevant package where the code lives is installed. (e.g., as long as `langchain_community` is installed.)
+
+However, we advise for users to not rely on these imports and instead migrate to the new imports. To help with this process, we’re releasing a migration script via the LangChain CLI. See further instructions in migration guide.
+
+1. Code that has better alternatives available and will eventually be removed, so there’s only a single way to do things. (e.g., `predict_messages` method in ChatModels has been deprecated in favor of `invoke`).
+
+Many of these were marked for removal in 0.2. We have bumped the removal to 0.3.

+
+This section contains introductions to key parts of LangChain.
+
+## Architecture
+
+LangChain as a framework consists of a number of packages.
+
+### `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.
+
+### 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.
+
+### `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.
+
+### [`langgraph`](/docs/langgraph)
+
+`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. Makes it easy to get a production ready API up and running.
+
+### [LangSmith](/docs/langsmith)
+
+A developer platform that lets you debug, test, evaluate, and monitor LLM applications.

+
+## LangChain Expression Language (LCEL)
+
+LangChain Expression Language, or LCEL, is a declarative way to chain LangChain components.
+LCEL was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully run LCEL chains with 100s of steps in production). 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).
+
+### Runnable 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.
+
+### 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.
+
+### 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.
+
+### Messages
+
+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                                                                                                                                                                                                                                              |

+
+### 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.
+
+### Documents
+
+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).
+
+### Vector stores
+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.
+
+Vector stores 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.
+
+### Tools
+Tools are interfaces that an agent, chain, or LLM can use to interact with the world.
+They combine a few things:
+
+1. The name of the tool
+2. A description of what the tool is
+3. JSON schema of what the inputs to the tool are
+4. The function to call
+5. 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)
+
+## Techniques
+
+### 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/tutorials/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/)

 - The developer lands on https://python.langchain.com, and reads through the introduction and the diagram.

 - If they have a specific task in mind that they want to accomplish, they will be drawn to the Use-Case section. The use-case should provide a good, concrete hook that shows the value LangChain can provide them and be a good entrypoint to the framework.
 - They can then move to learn more about the fundamentals of LangChain through the Expression Language sections.
 - Next, they can learn about LangChain's various components and integrations.

-       "'While Scrum has its potential cons and challenges, many organizations have successfully embraced and implemented this project management framework to great effect. 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.'"

-# LangChain Expression Language (LCEL)
-
-LangChain Expression Language, or LCEL, is a declarative way to easily compose chains together.
-LCEL was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully run LCEL chains with 100s of steps in production). 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/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**](/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. 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**](/docs/expression_language/interface#input-schema)
-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).

-# 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";
-
-<Tabs>
-  <TabItem value="pip" label="Pip" default>
-    <CodeBlock language="bash">pip install langchain</CodeBlock>
-  </TabItem>
-  <TabItem value="conda" label="Conda">
-    <CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
-  </TabItem>
-</Tabs>
-
-
-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.
-
-<Tabs>
-  <TabItem value="openai" label="OpenAI" default>
-
-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="...")
-```
-
-  </TabItem>
-  <TabItem value="local" label="Local (using Ollama)">
-
-[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")
-```
-
-  </TabItem>
-  <TabItem value="anthropic" label="Anthropic">
-
-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="...")
-```
-
-  </TabItem>
-  <TabItem value="cohere" label="Cohere">
-
-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="...")
-```
-
-  </TabItem>
-</Tabs>
-
-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 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.
-
-<Tabs>
-  <TabItem value="openai" label="OpenAI (API)" default>
-  
-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()
-```
-
-</TabItem>
-<TabItem value="local" label="Local (using Ollama)">
-
-Make sure you have Ollama running (same set up as with the LLM).
-
-```python
-from langchain_community.embeddings import OllamaEmbeddings
-
-embeddings = OllamaEmbeddings()
-```
-  </TabItem>
-<TabItem value="cohere" label="Cohere (API)" default>
-
-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()
-```
-
-</TabItem>
-</Tabs>
-
-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>
-{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. Load Retriever
-loader = WebBaseLoader("https://docs.smith.langchain.com/user_guide")
-docs = loader.load()
-text_splitter = RecursiveCharacterTextSplitter()
-documents = text_splitter.split_documents(docs)
-embeddings = OpenAIEmbeddings()
-vector = FAISS.from_documents(documents, embeddings)
-retriever = vector.as_retriever()
-
-# 2. Create Tools
-retriever_tool = create_retriever_tool(
-    retriever,
-    "langsmith_search",
-    "Search for information about LangSmith. For any questions about LangSmith, you must use this tool!",
-)
-search = TavilySearchResults()
-tools = [retriever_tool, search]
-
-
-# 3. Create Agent
-prompt = hub.pull("hwchase17/openai-functions-agent")
-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)
-
-
-# 4. App definition
-app = FastAPI(
-  title="LangChain Server",
-  version="1.0",
-  description="A simple API server using LangChain's Runnable interfaces",
-)
-
-# 5. Adding chain route
-
-# We need to add these input/output schemas because the current AgentExecutor
-# is lacking in schemas.
-
-class Input(BaseModel):
-    input: str
-    chat_history: List[BaseMessage] = Field(
-        ...,
-        extra={"widget": {"type": "chat", "input": "location"}},
-    )
-
-
-class Output(BaseModel):
-    output: str
-
-add_routes(
-    app,
-    agent_executor.with_types(input_type=Input, output_type=Output),
-    path="/agent",
-)
-
-if __name__ == "__main__":
-    import uvicorn
-
-    uvicorn.run(app, host="localhost", port=8000)
-```
-
-And that's it! If we execute this file:
-```bash
-python serve.py
-```
-we should see our chain being served at localhost:8000.
-
-### Playground
-
-Every LangServe service comes with a simple built-in UI for configuring and invoking the application with streaming output and visibility into intermediate steps.
-Head to http://localhost:8000/agent/playground/ to try it out! Pass in the same question as before - "how can langsmith help with testing?" - and it should respond same as before.
-
-### Client
-
-Now let's set up a client for programmatically interacting with our service. We can easily do this with the `[langserve.RemoteRunnable](/docs/langserve#client)`.
-Using this, we can interact with the served chain as if it were running client-side.
-
-```python
-from langserve import RemoteRunnable
-
-remote_chain = RemoteRunnable("http://localhost:8000/agent/")
-remote_chain.invoke({
-    "input": "how can langsmith help with testing?",
-    "chat_history": []  # Providing an empty list as this is the first call
-})
-```
-
-To learn more about the many other features of LangServe [head here](/docs/langserve).
-
-## Next steps
-
-We've touched on how to build an application with LangChain, how to trace it with LangSmith, and how to serve it with LangServe.
-There are a lot more features in all three of these than we can cover here.
-To continue on your journey, we recommend you read the following (in order):
-
-- All of these features are backed by [LangChain Expression Language (LCEL)](/docs/expression_language) - a way to chain these components together. Check out that documentation to better understand how to create custom chains.
-- [Model IO](/docs/modules/model_io) covers more details of prompts, LLMs, and output parsers.
-- [Retrieval](/docs/modules/data_connection) covers more details of everything related to retrieval
-- [Agents](/docs/modules/agents) covers details of everything related to agents
-- Explore common [end-to-end use cases](/docs/use_cases/) and [template applications](/docs/templates)
-- [Read up on LangSmith](/docs/langsmith/), the platform for debugging, testing, monitoring and more
-- Learn more about serving your applications with [LangServe](/docs/langserve)

-# Debugging
-
-If you're building with LLMs, at some point something will break, and you'll need to debug. A model call will fail, or the model output will be misformatted, or there will be some nested model calls and it won't be clear where along the way an incorrect output was created.
-
-Here are a few different tools and functionalities to aid in debugging.
-
-
-
-## Tracing
-
-Platforms with tracing capabilities like [LangSmith](/docs/langsmith/) are the most comprehensive solutions for debugging. These platforms make it easy to not only log and visualize LLM apps, but also to actively debug, test and refine them.
-
-When building production-grade LLM applications, platforms like this are essential.
-
-![Screenshot of the LangSmith debugging interface showing an AgentExecutor run with input and output details, and a run tree visualization.](../../../static/img/run_details.png "LangSmith Debugging Interface")
-
-## `set_debug` and `set_verbose`
-
-If you're prototyping in Jupyter Notebooks or running Python scripts, it can be helpful to print out the intermediate steps of a Chain run. 
-
-There are a number of ways to enable printing at varying degrees of verbosity.
-
-Let's suppose we have a simple agent, and want to visualize the actions it takes and tool outputs it receives. Without any debugging, here's what we see:
-
-
-```python
-from langchain.agents import AgentType, initialize_agent, load_tools
-from langchain_openai import ChatOpenAI
-
-llm = ChatOpenAI(model="gpt-4", temperature=0)
-tools = load_tools(["ddg-search", "llm-math"], llm=llm)
-agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
-```
-
-
-```python
-agent.run("Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?")
-```
-
-<CodeOutputBlock lang="python">
-
-```
-    'The director of the 2023 film Oppenheimer is Christopher Nolan and he is approximately 19345 days old in 2023.'
-```
-
-</CodeOutputBlock>
-
-### `set_debug(True)`
-
-Setting the global `debug` flag will cause all LangChain components with callback support (chains, models, agents, tools, retrievers) to print the inputs they receive and outputs they generate. This is the most verbose setting and will fully log raw inputs and outputs.
-
-
-```python
-from langchain.globals import set_debug
-
-set_debug(True)
-
-agent.run("Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?")

-## Other callbacks
-
-`Callbacks` are what we use to execute any functionality within a component outside the primary component logic. All of the above solutions use `Callbacks` under the hood to log intermediate steps of components. There are a number of `Callbacks` relevant for debugging that come with LangChain out of the box, like the [FileCallbackHandler](/docs/modules/callbacks/filecallbackhandler). You can also implement your own callbacks to execute custom functionality.

-- v2 contains has a number of breaking changes (https://docs.pydantic.dev/2.0/migration/)
-- Pydantic v2 and v1 are under the same package name, so both versions cannot be installed at the same time
-
-## LangChain Pydantic migration plan
-
-As of `langchain>=0.0.267`, LangChain will allow users to install either Pydantic V1 or V2. 
-   * Internally LangChain will continue to [use V1](https://docs.pydantic.dev/latest/migration/#continue-using-pydantic-v1-features).
-   * During this time, users can pin their pydantic version to v1 to avoid breaking changes, or start a partial
-   migration using pydantic v2 throughout their code, but avoiding mixing v1 and v2 code for LangChain (see below).
-
-User can either pin to pydantic v1, and upgrade their code in one go once LangChain has migrated to v2 internally, or they can start a partial migration to v2, but must avoid mixing v1 and v2 code for LangChain.
-
-Below are two examples of showing how to avoid mixing pydantic v1 and v2 code in
-the case of inheritance and in the case of passing objects to LangChain.
-
-**Example 1: Extending via inheritance**
-
-**YES** 
-
-```python
-from pydantic.v1 import root_validator, validator
-
-class CustomTool(BaseTool): # BaseTool is v1 code
-    x: int = Field(default=1)
-
-    def _run(*args, **kwargs):
-        return "hello"
-
-    @validator('x') # v1 code
-    @classmethod
-    def validate_x(cls, x: int) -> int:
-        return 1
-    
-
-CustomTool(
-    name='custom_tool',
-    description="hello",
-    x=1,
-)
-```
-
-Mixing Pydantic v2 primitives with Pydantic v1 primitives can raise cryptic errors
-
-**NO** 
-
-```python
-from pydantic import Field, field_validator # pydantic v2
-
-class CustomTool(BaseTool): # BaseTool is v1 code
-    x: int = Field(default=1)

-    
-
-CustomTool(

-# Deployment
-
-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.

-# Comparison Evaluators
-
-Comparison evaluators in LangChain help measure two different chains or LLM outputs. These evaluators are helpful for comparative analyses, such as A/B testing between two language models, or comparing different versions of the same model. They can also be useful for things like generating preference scores for ai-assisted reinforcement learning.
-
-These evaluators inherit from the `PairwiseStringEvaluator` class, providing a comparison interface for two strings - typically, the outputs from two different prompts or models, or two versions of the same model. In essence, a comparison evaluator performs an evaluation on a pair of strings and returns a dictionary containing the evaluation score and other relevant details.
-
-To create a custom comparison evaluator, inherit from the `PairwiseStringEvaluator` class and overwrite the `_evaluate_string_pairs` method. If you require asynchronous evaluation, also overwrite the `_aevaluate_string_pairs` method.
-
-Here's a summary of the key methods and properties of a comparison evaluator:
-
-- `evaluate_string_pairs`: Evaluate the output string pairs. This function should be overwritten when creating custom evaluators.
-- `aevaluate_string_pairs`: Asynchronously evaluate the output string pairs. This function should be overwritten for asynchronous evaluation.
-- `requires_input`: This property indicates whether this evaluator requires an input string.
-- `requires_reference`: This property specifies whether this evaluator requires a reference label.
-
-:::note LangSmith Support
-The [run_on_dataset](https://api.python.langchain.com/en/latest/langchain_api_reference.html#module-langchain.smith) evaluation method is designed to evaluate only a single model at a time, and thus, doesn't support these evaluators.
-:::
-
-Detailed information about creating custom evaluators and the available built-in comparison evaluators is provided in the following sections.

-# Evaluation
-
-Building applications with language models involves many moving parts. 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. We have published a number of benchmark tasks within the [LangChain Benchmarks](https://langchain-ai.github.io/langchain-benchmarks/) package to grade different LLM systems on tasks such as:
-
-- Agent tool use
-- Retrieval-augmented question-answering
-- Structured Extraction 
-
-Check out the docs for examples and leaderboard information.
-
-## Reference Docs
-
-For detailed information on the available evaluators, including how to instantiate, configure, and customize them, check out the [reference documentation](https://api.python.langchain.com/en/latest/langchain_api_reference.html#module-langchain.evaluation) directly.

-# String Evaluators
-
-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.

-# Trajectory Evaluators
-
-Trajectory Evaluators in LangChain provide a more holistic approach to evaluating an agent. These evaluators assess the full sequence of actions taken by an agent and their corresponding responses, which we refer to as the "trajectory". This allows you to better measure an agent's effectiveness and capabilities.
-
-A Trajectory Evaluator implements the `AgentTrajectoryEvaluator` interface, which requires two main methods:
-
-- `evaluate_agent_trajectory`: This method synchronously evaluates an agent's trajectory.
-- `aevaluate_agent_trajectory`: This asynchronous counterpart allows evaluations to be run in parallel for efficiency.
-
-Both methods accept three main parameters:
-
-- `input`: The initial input given to the agent.
-- `prediction`: The final predicted response from the agent.
-- `agent_trajectory`: The intermediate steps taken by the agent, given as a list of tuples.
-
-These methods return a dictionary. It is recommended that custom implementations return a `score` (a float indicating the effectiveness of the agent) and `reasoning` (a string explaining the reasoning behind the score).
-
-You can capture an agent's trajectory by initializing the agent with the `return_intermediate_steps=True` parameter. This lets you collect all intermediate steps without relying on special callbacks.
-
-For a deeper dive into the implementation and use of Trajectory Evaluators, refer to the sections below.

-# Constitutional chain
-
-This example shows the Self-critique chain with `Constitutional AI`.
-
-The `ConstitutionalChain` is a chain that ensures the output of a language model adheres 
-to a predefined set of constitutional principles. By incorporating specific rules and guidelines, 
-the `ConstitutionalChain` filters and modifies the generated content to align with these principles, 
-thus providing more controlled, ethical, and contextually appropriate responses. 
-This mechanism helps maintain the integrity of the output while minimizing the risk of generating 
-content that may violate guidelines, be offensive, or deviate from the desired context.

-# Privacy & Safety
-
-One of the key concerns with using LLMs is that they may misuse private data or generate harmful or unethical text. This is an area of active research in the field. Here we present some built-in chains inspired by this research, which are intended to make the outputs of LLMs safer.

-- [Amazon Comprehend moderation chain](/docs/guides/productionization/safety/amazon_comprehend_chain): Use [Amazon Comprehend](https://aws.amazon.com/comprehend/) to detect and handle Personally Identifiable Information (PII) and toxicity.
-- [Constitutional chain](/docs/guides/productionization/safety/constitutional_chain): Prompt the model with a set of principles which should guide the model behavior.
-- [Hugging Face prompt injection identification](/docs/guides/productionization/safety/hugging_face_prompt_injection): Detect and handle prompt injection attacks. 
-- [Layerup Security](/docs/guides/productionization/safety/layerup_security): Easily mask PII & sensitive data, detect and mitigate 10+ LLM-based threat vectors, including PII & sensitive data, prompt injection, hallucination, abuse, and more.
-- [Logical Fallacy chain](/docs/guides/productionization/safety/logical_fallacy_chain): Checks the model output against logical fallacies to correct any deviation.
-- [Moderation chain](/docs/guides/productionization/safety/moderation): Check if any output text is harmful and flag it.
-- [Presidio data anonymization](/docs/guides/productionization/safety/presidio_data_anonymization): Helps to ensure sensitive data is properly managed and governed.

-# Layerup Security
-
-The [Layerup Security](https://uselayerup.com) integration allows you to secure your calls to any LangChain LLM, LLM chain or LLM agent. The LLM object wraps around any existing LLM object, allowing for a secure layer between your users and your LLMs.
-
-While the Layerup Security object is designed as an LLM, it is not actually an LLM itself, it simply wraps around an LLM, allowing it to adapt the same functionality as the underlying LLM.
-
-## Setup
-First, you'll need a Layerup Security account from the Layerup [website](https://uselayerup.com).
-
-Next, create a project via the [dashboard](https://dashboard.uselayerup.com), and copy your API key. We recommend putting your API key in your project's environment.
-
-Install the Layerup Security SDK:
-```bash
-pip install LayerupSecurity
-```
-
-And install LangChain Community:
-```bash
-pip install langchain-community
-```
-
-And now you're ready to start protecting your LLM calls with Layerup Security!
-
-```python
-from langchain_community.llms.layerup_security import LayerupSecurity
-from langchain_openai import OpenAI
-
-# Create an instance of your favorite LLM
-openai = OpenAI(
-    model_name="gpt-3.5-turbo",
-    openai_api_key="OPENAI_API_KEY",
-)
-
-# Configure Layerup Security
-layerup_security = LayerupSecurity(
-    # Specify a LLM that Layerup Security will wrap around
-    llm=openai,
-
-    # Layerup API key, from the Layerup dashboard
-    layerup_api_key="LAYERUP_API_KEY",

-    # Custom base URL, if self hosting
-    layerup_api_base_url="https://api.uselayerup.com/v1",
-
-    # List of guardrails to run on prompts before the LLM is invoked

-    # List of guardrails to run on responses from the LLM
-    response_guardrails=["layerup.hallucination"],

-    mask=False,
-
-    # Metadata for abuse tracking, customer tracking, and scope tracking.
-    metadata={"customer": "example@uselayerup.com"},

-            ).format(violation["offending_guardrail"])
-        }
-    ),

-# Logical Fallacy chain
-
-This example shows how to remove logical fallacies from model output.
-
-## Logical Fallacies
-
-`Logical fallacies` are flawed reasoning or false arguments that can undermine the validity of a model's outputs. 
-
-Examples include circular reasoning, false
-dichotomies, ad hominem attacks, etc.  Machine learning models are optimized to perform well on specific metrics like accuracy, perplexity, or loss. However, 
-optimizing for metrics alone does not guarantee logically sound reasoning.
-
-Language models can learn to exploit flaws in reasoning to generate plausible-sounding but logically invalid arguments.  When models rely on fallacies, their outputs become unreliable and untrustworthy, even if they achieve high scores on metrics. Users cannot depend on such outputs. Propagating logical fallacies can spread misinformation, confuse users, and lead to harmful real-world consequences when models are deployed in products or services.
-
-Monitoring and testing specifically for logical flaws is challenging unlike other quality issues. It requires reasoning about arguments rather than pattern matching.
-
-Therefore, it is crucial that model developers proactively address logical fallacies after optimizing metrics. Specialized techniques like causal modeling, robustness testing, and bias mitigation can help avoid flawed reasoning.  Overall, allowing logical flaws to persist makes models less safe and ethical. Eliminating fallacies ensures model outputs remain logically valid and aligned with human reasoning. This maintains user trust and mitigates risks.
-

-## Example

-```python
-# Imports
-from langchain_openai import OpenAI

-
-```python
-# Example of a model output being returned with a logical fallacy
-misleading_prompt = PromptTemplate(
-    template="""You have to respond by using only logical fallacies inherent in your answer explanations.

-Question: {question}

-
-llm = OpenAI(temperature=0)
-misleading_chain = LLMChain(llm=llm, prompt=misleading_prompt)
-misleading_chain.run(question="How do I know the earth is round?")
-```
-
-<CodeOutputBlock lang="python">
-
-```
-    'The earth is round because my professor said it is, and everyone believes my professor'
-```
-
-</CodeOutputBlock>
-
-
-```python
-fallacies = FallacyChain.get_fallacies(["correction"])
-fallacy_chain = FallacyChain.from_llm(
-    chain=misleading_chain,
-    logical_fallacies=fallacies,
-    llm=llm,
-    verbose=True,
-)
-
-fallacy_chain.run(question="How do I know the earth is round?")
-```
-
-<CodeOutputBlock lang="python">
-
-```
-
-
-    > Entering new FallacyChain chain...
-    Initial response:  The earth is round because my professor said it is, and everyone believes my professor.
-
-    Applying correction...
-
-    Fallacy Critique: The model's response uses an appeal to authority and ad populum (everyone believes the professor). Fallacy Critique Needed.
-
-    Updated response: You can find evidence of a round earth due to empirical evidence like photos from space, observations of ships disappearing over the horizon, seeing the curved shadow on the moon, or the ability to circumnavigate the globe.
-
-
-    > Finished chain.

-    "\n",
-    "## Use case\n",
-    "\n",
-    "Multi-language support in data pseudonymization is essential due to differences in language structures and cultural contexts. Different languages may have varying formats for personal identifiers. For example, the structure of names, locations and dates can differ greatly between languages and regions. Furthermore, non-alphanumeric characters, accents, and the direction of writing can impact pseudonymization processes. Without multi-language support, data could remain identifiable or be misinterpreted, compromising data privacy and accuracy. Hence, it enables effective and precise pseudonymization suited for global operations.\n",
-    "\n",
-    "## Overview\n",
-    "\n",
-    "PII detection in Microsoft Presidio relies on several components - in addition to the usual pattern matching (e.g. using regex), the analyser uses a model for Named Entity Recognition (NER) to extract entities such as:\n",
-    "- `PERSON`\n",
