+# Dev container
+
+This project includes a [dev container](https://containers.dev/), which lets you use a container as a full-featured dev environment.
+
+You can use the dev container configuration in this folder to build and run the app without needing to install any of its tools locally! You can use it in [GitHub Codespaces](https://github.com/features/codespaces) or the [VS Code Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).
+
+## GitHub Codespaces
+[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/hwchase17/langchain)
+
+You may use the button above, or follow these steps to open this repo in a Codespace:
+1. Click the **Code** drop-down menu at the top of https://github.com/hwchase17/langchain.
+1. Click on the **Codespaces** tab.
+1. Click **Create codespace on master** .
+
+For more info, check out the [GitHub documentation](https://docs.github.com/en/free-pro-team@latest/github/developing-online-with-codespaces/creating-a-codespace#creating-a-codespace).
+  
+## VS Code Dev Containers
+[![Open in Dev Containers](https://img.shields.io/static/v1?label=Dev%20Containers&message=Open&color=blue&logo=visualstudiocode)](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/hwchase17/langchain)
+
+If you already have VS Code and Docker installed, you can use the button above to get started. This will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.
+
+You can also follow these steps to open this repo in a container using the VS Code Dev Containers extension:
+
+1. If this is your first time using a development container, please ensure your system meets the pre-reqs (i.e. have Docker installed) in the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).
+
+2. Open a locally cloned copy of the code:
+
+   - Clone this repository to your local filesystem.
+   - Press <kbd>F1</kbd> and select the **Dev Containers: Open Folder in Container...** command.
+   - Select the cloned copy of this folder, wait for the container to start, and try things out!
+
+You can learn more in the [Dev Containers documentation](https://code.visualstudio.com/docs/devcontainers/containers).
+
+## Tips and tricks
+
+* If you are working with the same repository folder in a container and Windows, you'll want consistent line endings (otherwise you may see hundreds of changes in the SCM view). The `.gitattributes` file in the root of this repo will disable line ending conversion and should prevent this. See [tips and tricks](https://code.visualstudio.com/docs/devcontainers/tips-and-tricks#_resolving-git-line-ending-issues-in-containers-resulting-in-many-modified-files) for more info.
+* If you'd like to review the contents of the image used in this dev container, you can check it out in the [devcontainers/images](https://github.com/devcontainers/images/tree/main/src/python) repo.

-# Tracing
-
-By enabling tracing in your LangChain runs, you’ll be able to more effectively visualize, step through, and debug your chains and agents.
-
-First, you should install tracing and set up your environment properly.
-You can use either a locally hosted version of this (uses Docker) or a cloud hosted version (in closed alpha).
-If you're interested in using the hosted platform, please fill out the form [here](https://forms.gle/tRCEMSeopZf6TE3b6).
-
-- [Locally Hosted Setup](../tracing/local_installation.md)
-- [Cloud Hosted Setup](../tracing/hosted_installation.md)
-
-## Tracing Walkthrough
-
-When you first access the UI, you should see a page with your tracing sessions.
-An initial one "default" should already be created for you.
-A session is just a way to group traces together.
-If you click on a session, it will take you to a page with no recorded traces that says "No Runs."
-You can create a new session with the new session form.
-
-![](../tracing/homepage.png)
-
-If we click on the `default` session, we can see that to start we have no traces stored.
-
-![](../tracing/default_empty.png)
-
-If we now start running chains and agents with tracing enabled, we will see data show up here.
-To do so, we can run [this notebook](../tracing/agent_with_tracing.ipynb) as an example.
-After running it, we will see an initial trace show up.
-
-![](../tracing/first_trace.png)
-
-From here we can explore the trace at a high level by clicking on the arrow to show nested runs.
-We can keep on clicking further and further down to explore deeper and deeper.
-
-![](../tracing/explore.png)
-
-We can also click on the "Explore" button of the top level run to dive even deeper.
-Here, we can see the inputs and outputs in full, as well as all the nested traces.
-
-![](../tracing/explore_trace.png)
-
-We can keep on exploring each of these nested traces in more detail.
-For example, here is the lowest level trace with the exact inputs/outputs to the LLM.
-
-![](../tracing/explore_llm.png)
-
-## Changing Sessions
-
-1. To initially record traces to a session other than `"default"`, you can set the `LANGCHAIN_SESSION` environment variable to the name of the session you want to record to:
-
-```python
-import os
-os.environ["LANGCHAIN_TRACING"] = "true"
-os.environ["LANGCHAIN_SESSION"] = "my_session" # Make sure this session actually exists. You can create a new session in the UI.
-```
-
-2. To switch sessions mid-script or mid-notebook, do NOT set the `LANGCHAIN_SESSION` environment variable. Instead: `langchain.set_tracing_callback_manager(session_name="my_session")`

+# Introduction
+
+**LangChain** is a framework for developing applications powered by language models. It enables applications that are:
+- **Data-aware**: connect a language model to other sources of data
+- **Agentic**: allow a language model to interact with its environment
+
+The main value props of LangChain are:
+1. **Components**: abstractions for working with language models, along with a collection of implementations for each abstraction. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not
+2. **Off-the-shelf chains**: a structured assembly of components for accomplishing specific higher-level tasks
+
+Off-the-shelf chains make it easy to get started. For more complex applications and nuanced use-cases, components make it easy to customize existing chains or build new ones.
+
+## Get started
+
+[Here’s](/docs/get_started/installation.html) how to install LangChain, set up your environment, and start building.
+
+We recommend following our [Quickstart](/docs/get_started/quickstart.html) guide to familiarize yourself with the framework by building your first LangChain application.
+
+_**Note**: These docs are for the LangChain [Python package](https://github.com/hwchase17/langchain). For documentation on [LangChain.js](https://github.com/hwchase17/langchainjs), the JS/TS version, [head here](https://js.langchain.com/docs)._
+
+## Modules

+
+#### [Model I/O](/docs/modules/model_io/)
+Interface with language models
+#### [Data connection](/docs/modules/data_connection/)
+Interface with application-specific data
+#### [Chains](/docs/modules/chains/)
+Construct sequences of calls
+#### [Agents](/docs/modules/agents/)
+Let chains choose which tools to use given high-level directives
+#### [Memory](/docs/modules/memory/)
+Persist application state between runs of a chain
+#### [Callbacks](/docs/modules/callbacks/)
+Log and stream intermediate steps of any chain
+

+# Quickstart
+
+## Installation
+
+To install LangChain run:
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+import Install from "@snippets/get_started/quickstart/installation.mdx"
+
+<Install/>
+
+For more details, see our [Installation guide](/docs/get_started/installation.html).
+
+## Environment setup
+
+Using LangChain will usually require integrations with one or more model providers, data stores, APIs, etc. For this example, we'll use OpenAI's model APIs.
+
+import OpenAISetup from "@snippets/get_started/quickstart/openai_setup.mdx"
+
+<OpenAISetup/>
+
+## Building an application
+
+Now we can start building our language model application. LangChain provides many modules that can be used to build language model applications. Modules can be used as stand-alones in simple applications and they can be combined for more complex use cases.
+
+## LLMs
+#### Get predictions from a language model
+
+The basic building block of LangChain is the LLM, which takes in text and generates more text.
+
+As an example, suppose we're building an application that generates a company name based on a company description. In order to do this, we need to initialize an OpenAI model wrapper. In this case, since we want the outputs to be MORE random, we'll initialize our model with a HIGH temperature.
+
+import LLM from "@snippets/get_started/quickstart/llm.mdx"
+
+<LLM/>
+
+## Chat models
+
+Chat models are a variation on language models. While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a "text in, text out" API, they expose an interface where "chat messages" are the inputs and outputs.
+
+You can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are `AIMessage`, `HumanMessage`, `SystemMessage`, and `ChatMessage` -- `ChatMessage` takes in an arbitrary role parameter. Most of the time, you'll just be dealing with `HumanMessage`, `AIMessage`, and `SystemMessage`.
+
+import ChatModel from "@snippets/get_started/quickstart/chat_model.mdx"
+
+<ChatModel/>
+
+## Prompt templates
+
+Most LLM applications do not pass user input directly into to an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand.
+
+In the previous example, the text we passed to the model contained instructions to generate a company name. For our application, it'd be great if the user only had to provide the description of a company/product, without having to worry about giving the model instructions.
+
+import PromptTemplateLLM from "@snippets/get_started/quickstart/prompt_templates_llms.mdx"
+import PromptTemplateChatModel from "@snippets/get_started/quickstart/prompt_templates_chat_models.mdx"
+
+<Tabs>
+    <TabItem value="llms" label="LLMs" default>
+
+With PromptTemplates this is easy! In this case our template would be very simple:
+
+<PromptTemplateLLM/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
+
+Similar to LLMs, you can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplate`s. You can use `ChatPromptTemplate`'s `format_messages` method to generate the formatted messages.
+
+Because this is generating a list of messages, it is slightly more complex than the normal prompt template which is generating only a string. Please see the detailed guides on prompts to understand more options available to you here.
+
+<PromptTemplateChatModel/>
+    </TabItem>
+</Tabs>
+
+## Chains
+
+Now that we've got a model and a prompt template, we'll want to combine the two. Chains give us a way to link (or chain) together multiple primitives, like models, prompts, and other chains.
+
+import ChainLLM from "@snippets/get_started/quickstart/chains_llms.mdx"
+import ChainChatModel from "@snippets/get_started/quickstart/chains_chat_models.mdx"
+
+<Tabs>
+<TabItem value="llms" label="LLMs" default>
+
+The simplest and most common type of chain is an LLMChain, which passes an input first to a PromptTemplate and then to an LLM. We can construct an LLM chain from our existing model and prompt template.
+
+<ChainLLM/>
+
+There we go, our first chain! Understanding how this simple chain works will set you up well for working with more complex chains.
+
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
+
+The `LLMChain` can be used with chat models as well:
+
+<ChainChatModel/>
+</TabItem>
+</Tabs>
+
+## Agents
+
+import AgentLLM from "@snippets/get_started/quickstart/agents_llms.mdx"
+import AgentChatModel from "@snippets/get_started/quickstart/agents_chat_models.mdx"
+
+Our first chain ran a pre-determined sequence of steps. To handle complex workflows, we need to be able to dynamically choose actions based on inputs.
+
+Agents do just this: they use a language model to determine which actions to take and in what order. Agents are given access to tools, and they repeatedly choose a tool, run the tool, and observe the output until they come up with a final answer.
+
+To load an agent, you need to choose a(n):
+- LLM/Chat model: The language model powering the agent.
+- Tool(s): A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. For a list of predefined tools and their specifications, see the [Tools documentation](/docs/modules/agents/tools/).
+- Agent name: A string that references a supported agent class. An agent class is largely parameterized by the prompt the language model uses to determine which action to take. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see [here](/docs/modules/agents/how_to/custom_agent.html). For a list of supported agents and their specifications, see [here](/docs/modules/agents/agent_types/).
+
+For this example, we'll be using SerpAPI to query a search engine.
+
+You'll need to install the SerpAPI Python package:
+
+```bash
+pip install google-search-results
+```
+
+And set the `SERPAPI_API_KEY` environment variable.
+
+<Tabs>
+<TabItem value="llms" label="LLMs" default>
+<AgentLLM/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
+
+Agents can also be used with chat models, you can initialize one using `AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION` as the agent type.
+
+<AgentChatModel/>
+</TabItem>
+</Tabs>
+
+## Memory
+
+The chains and agents we've looked at so far have been stateless, but for many applications it's necessary to reference past interactions. This is clearly the case with a chatbot for example, where you want it to understand new messages in the context of past messages.
+
+The Memory module gives you a way to maintain application state. The base Memory interface is simple: it lets you update state given the latest run inputs and outputs and it lets you modify (or contextualize) the next input using the stored state.
+
+There are a number of built-in memory systems. The simplest of these are is a buffer memory which just prepends the last few inputs/outputs to the current input - we will use this in the example below.
+
+import MemoryLLM from "@snippets/get_started/quickstart/memory_llms.mdx"
+import MemoryChatModel from "@snippets/get_started/quickstart/memory_chat_models.mdx"
+
+<Tabs>
+<TabItem value="llms" label="LLMs" default>
+
+<MemoryLLM/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
+
+You can use Memory with chains and agents initialized with chat models. The main difference between this and Memory for LLMs is that rather than trying to condense all previous messages into a string, we can keep them as their own unique memory object.
+
+<MemoryChatModel/>
+
+</TabItem>
+</Tabs>

+# Agent types
+
+## Action agents
+
+Agents use an LLM to determine which actions to take and in what order.
+An action can either be using a tool and observing its output, or returning a response to the user.
+Here are the agents available in LangChain.
+
+### [Zero-shot ReAct](/docs/modules/agents/agent_types/react.html)
+
+This agent uses the [ReAct](https://arxiv.org/pdf/2205.00445.pdf) framework to determine which tool to use
+based solely on the tool's description. Any number of tools can be provided.
+This agent requires that a description is provided for each tool.
+
+**Note**: This is the most general purpose action agent.
+
+### [Structured input ReAct](/docs/modules/agents/agent_types/structured_chat.html)
+
+The structured tool chat agent is capable of using multi-input tools.
+Older agents are configured to specify an action input as a single string, but this agent can use a tools' argument
+schema to create a structured action input. This is useful for more complex tool usage, like precisely
+navigating around a browser.
+
+### [OpenAI Functions](/docs/modules/agents/agent_types/openai_functions_agent.html)
+
+Certain OpenAI models (like gpt-3.5-turbo-0613 and gpt-4-0613) have been explicitly fine-tuned to detect when a
+function should to be called and respond with the inputs that should be passed to the function.
+The OpenAI Functions Agent is designed to work with these models.
+
+### [Conversational](/docs/modules/agents/agent_types/chat_conversation_agent.html)
+
+This agent is designed to be used in conversational settings.
+The prompt is designed to make the agent helpful and conversational.
+It uses the ReAct framework to decide which tool to use, and uses memory to remember the previous conversation interactions.
+
+### [Self ask with search](/docs/modules/agents/agent_types/self_ask_with_search.html)
+
+This agent utilizes a single tool that should be named `Intermediate Answer`.
+This tool should be able to lookup factual answers to questions. This agent
+is equivalent to the original [self ask with search paper](https://ofir.io/self-ask.pdf),
+where a Google search API was provided as the tool.
+
+### [ReAct document store](/docs/modules/agents/agent_types/react_docstore.html)
+
+This agent uses the ReAct framework to interact with a docstore. Two tools must
+be provided: a `Search` tool and a `Lookup` tool (they must be named exactly as so).
+The `Search` tool should search for a document, while the `Lookup` tool should lookup
+a term in the most recently found document.
+This agent is equivalent to the
+original [ReAct paper](https://arxiv.org/pdf/2210.03629.pdf), specifically the Wikipedia example.
+
+## [Plan-and-execute agents](/docs/modules/agents/agent_types/plan_and_execute.html)
+Plan and execute agents accomplish an objective by first planning what to do, then executing the sub tasks. This idea is largely inspired by [BabyAGI](https://github.com/yoheinakajima/babyagi) and then the ["Plan-and-Solve" paper](https://arxiv.org/abs/2305.04091).

+In an API call, you can describe functions and have the model intelligently choose to output a JSON object containing arguments to call those functions.
+The goal of the OpenAI Function APIs is to more reliably return valid and useful function calls than a generic text completion or chat API.

+# Agents
+
+Some applications require a flexible chain of calls to LLMs and other tools based on user input. The **Agent** interface provides the flexibility for such applications. An agent has access to a suite of tools, and determines which ones to use depending on the user input. Agents can use multiple tools, and use the output of one tool as the input to the next.
+
+There are two main types of agents:
+
+- **Action agents**: at each timestep, decide on the next action using the outputs of all previous actions
+- **Plan-and-execute agents**: decide on the full sequence of actions up front, then execute them all without updating the plan
+
+Action agents are suitable for small tasks, while plan-and-execute agents are better for complex or long-running tasks that require maintaining long-term objectives and focus. Often the best approach is to combine the dynamism of an action agent with the planning abilities of a plan-and-execute agent by letting the plan-and-execute agent use action agents to execute plans.
+
+For a full list of agent types see [agent types](/docs/modules/agents/agent_types/). Additional abstractions involved in agents are:
+- [**Tools**](/docs/modules/agents/tools/): the actions an agent can take. What tools you give an agent highly depend on what you want the agent to do
+- [**Toolkits**](/docs/modules/agents/toolkits/): wrappers around collections of tools that can be used together a specific use case. For example, in order for an agent to
+  interact with a SQL database it will likely need one tool to execute queries and another to inspect tables
+
+## Action agents
+
+At a high-level an action agent:
+1. Receives user input
+2. Decides which tool, if any, to use and the tool input
+3. Calls the tool and records the output (also known as an "observation")
+4. Decides the next step using the history of tools, tool inputs, and observations
+5. Repeats 3-4 until it determines it can respond directly to the user
+
+Action agents are wrapped in **agent executors**, which are responsible for calling the agent, getting back an action and action input, calling the tool that the action references with the generated input, getting the output of the tool, and then passing all that information back into the agent to get the next action it should take.
+
+Although an agent can be constructed in many ways, it typically involves these components:
+
+- **Prompt template**: Responsible for taking the user input and previous steps and constructing a prompt
+  to send to the language model
+- **Language model**: Takes the prompt with use input and action history and decides what to do next
+- **Output parser**: Takes the output of the language model and parses it into the next action or a final answer
+
+## Plan-and-execute agents
+
+At a high-level a plan-and-execute agent:
+1. Receives user input
+2. Plans the full sequence of steps to take
+3. Executes the steps in order, passing the outputs of past steps as inputs to future steps
+
+The most typical implementation is to have the planner be a language model, and the executor be an action agent. Read more [here](/docs/modules/agents/agent_types/plan_and_execute.html).

+# 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.

+# Moderation
+This notebook walks through examples of how to use a moderation chain, and several common ways for doing so. Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, [specifically prohibit](https://beta.openai.com/docs/usage-policies/use-case-policy) you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.
+
+If the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful. There could even be other ways to handle it! We will cover all these ways in this walkthrough.

+The refine documents chain constructs a response by looping over the input documents and iteratively updating its answer. For each document, it passes all non-document inputs, the current document, and the latest intermediate answer to an LLM chain to get a new answer.
+
+Since the Refine chain only passes a single document to the LLM at a time, it is well-suited for tasks that require analyzing more documents than can fit in the model's context.
+The obvious tradeoff is that this chain will make far more LLM calls than, for example, the Stuff documents chain.
+There are also certain tasks which are difficult to accomplish iteratively. For example, the Refine chain can perform poorly when documents frequently cross-reference one another or when a task requires detailed information from many documents.
