 ## 🚀 Quick Start
 
-> **Note:** You can run this repository locally (which is described below) or in a [development container](https://containers.dev/) (which is described in the [.devcontainer folder](https://github.com/hwchase17/langchain/tree/master/.devcontainer)).
+This quick start describes running the repository locally.
+For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/hwchase17/langchain/tree/master/.devcontainer).
 
-This project uses [Poetry](https://python-poetry.org/) v1.5.1 as a dependency manager. Check out Poetry's [documentation on how to install it](https://python-poetry.org/docs/#installation) on your system before proceeding.
+### Dependency Management: Poetry and other env/dependency managers
 
-❗Note: If you use `Conda` or `Pyenv` as your environment / package manager, avoid dependency conflicts by doing the following first:
-1. *Before installing Poetry*, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
-2. Install Poetry v1.5.1 (see above)
-3. Tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
-4. Continue with the following steps.

+
+### Core vs. Experimental
 
 There are two separate projects in this repository:
 - `langchain`: core langchain code, abstractions, and use cases
-- `langchain.experimental`: more experimental code
+- `langchain.experimental`: see the [Experimental README](../libs/experimental/README.md) for more information.
 
-Each of these has their OWN development environment.
-In order to run any of the commands below, please move into their respective directories.
-For example, to contribute to `langchain` run `cd libs/langchain` before getting started with the below.
+Each of these has their own development environment. Docs are run from the top-level makefile, but development
+is split across separate test & release flows.
 
-To install requirements:
+For this quickstart, start with langchain core:
+
+```bash
+cd libs/langchain
+```
+
+### Local Development Dependencies
+
+Install langchain development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):
 
 ```bash
 poetry install --with test
 ```
 
-This will install all requirements for running the package, examples, linting, formatting, tests, and coverage.
+Then verify dependency installation:
 
-❗Note: If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running Poetry v1.5.1. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases. If you are still seeing this bug on v1.5.1, you may also try disabling "modern installation" (`poetry config installer.modern-installation false`) and re-installing requirements. See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
+```bash
+make test
+```
 
-Now assuming `make` and `pytest` are installed, you should be able to run the common tasks in the following section. To double check, run `make test` under `libs/langchain`, all tests should pass. If they don't, you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.

+All LLMs implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all LLMs basic support for async, streaming and batch, which by default is implemented as below:
+- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the LLM is being executed, by moving this call to a background thread.
+- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying LLM provider. This obviously doesn't give you token-by-token streaming, which requires native support from the LLM provider, but ensures your code that expects an iterator of tokens can work for any of our LLM integrations.
+- *Batch* support defaults to calling the underlying LLM in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
+
+Each LLM integration can optionally provide native implementations for async, streaming or batch, which, for providers that support it, can be more efficient. The table shows, for each integration, which features have been implemented with native support.

 # LangChain Expression Language (LCEL)
 
 LangChain Expression Language or LCEL is a declarative way to easily compose chains together.
-Any chain constructed this way will automatically have full sync, async, and streaming support.
+There are several benefits to writing chains in this manner (as opposed to writing normal code):
+
+**Async, Batch, and Streaming Support**
+Any chain constructed this way will automatically have full sync, async, batch, and streaming support.
+This makes it easy to prototype a chain in a Jupyter notebook using the sync interface, and then expose it as an async streaming interface.
+
+**Fallbacks**
+The non-determinism of LLMs makes it important to be able to handle errors gracefully.
+With LCEL you can easily attach fallbacks to any chain.
+
+**Parallelism**
+Since LLM applications involve (sometimes long) API calls, it often becomes important to run things in parallel.
+With LCEL syntax, any components that can be run in parallel automatically are.
+
+**Seamless LangSmith Tracing Integration**
+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](https://smith.langchain.com) for maximal observability and debuggability.

 # 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
+**LangChain** is a framework for developing applications powered by language models. It enables applications that:
+- **Are context-aware**: connect a language model to sources of context (prompt instructions, few shot examples, content to ground its response in, etc.)
+- **Reason**: rely on a language model to reason (about how to answer based on provided context, what actions to take, etc.)
 
 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.

 - LLM: The language model is the core reasoning engine here. In order to work with LangChain, you need to understand the different types of language models and how to work with them.
 - Prompt Templates: This provides instructions to the language model. This controls what the language model outputs, so understanding how to construct prompts and different prompting strategies is crucial.
 - Output Parsers: These translate the raw response from the LLM to a more workable format, making it easy to use the output downstream.

-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.
-
-The OpenAI Functions Agent is designed to work with these models.

-# Plan-and-execute

-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).
-
-The planning is almost always done by an LLM.

@@ -7,20 +7,27 @@ The core idea of agents is to use an LLM to choose a sequence of actions to take
 In chains, a sequence of actions is hardcoded (in code).
 In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.
 
+Some important terminology (and schema) to know:
+
+1. `AgentAction`: This is a dataclass that represents the action an agent should take. It has a `tool` property (which is the name of the tool that should be invoked) and a `tool_input` property (the input to that tool)
+2. `AgentFinish`: This is a dataclass that signifies that the agent has finished and should return to the user. It has a `return_values` parameter, which is a dictionary to return. It often only has one key - `output` - that is a string, and so often it is just this key that is returned.
+3. `intermediate_steps`: These represent previous agent actions and corresponding outputs that are passed around. These are important to pass to future iteration so the agent knows what work it has already done. This is typed as a `List[Tuple[AgentAction, Any]]`. Note that observation is currently left as type `Any` to be maximally flexible. In practice, this is often a string.
+
 There are several key components here:
 
 ## Agent
 
-This is the class responsible for deciding what step to take next.
+This is the chain responsible for deciding what step to take next.
 This is powered by a language model and a prompt.
-This prompt can include things like:
+The inputs to this chain are:
 
-1. The personality of the agent (useful for having it respond in a certain way)
-2. Background context for the agent (useful for giving it more context on the types of tasks it's being asked to do)
-3. Prompting strategies to invoke better reasoning (the most famous/widely used being [ReAct](https://arxiv.org/abs/2210.03629))
+1. List of available tools
+2. User input
+3. Any previously executed steps (`intermediate_steps`)
 
-LangChain provides a few different types of agents to get started.
-Even then, you will likely want to customize those agents with parts (1) and (2).
+This chain then returns either the next action to take or the final response to send to the user (`AgentAction` or `AgentFinish`).
+
+Different agents have different prompting styles for reasoning, different ways of encoding input, and different ways of parsing the output.

You can prompt the start of a conversation by saying something like \"Let\\'s discuss machine learning\"\\n\\n- Ask for summaries or high-level explanations on subjects. For example \"Can you summarize the main themes in Shakespeare\\'s Hamlet?\" \\n\\n- Give creative writing prompts or requests to have LangChain generate text in different styles. For example \"Write a short children\\'s story about a mouse\" or \"Generate a poem in the style of Robert Frost about nature\"\\n\\n- Correct LangChain if it makes an inaccurate statement and provide the right information.

 # Chat models
 
 import DocCardList from "@theme/DocCardList";
 
+## Features (natively supported)
+All ChatModels implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all ChatModels basic support for async, streaming and batch, which by default is implemented as below:
+- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the ChatModel is being executed, by moving this call to a background thread.
+- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying ChatModel provider. This obviously doesn't give you token-by-token streaming, which requires native support from the ChatModel provider, but ensures your code that expects an iterator of tokens can work for any of our ChatModel integrations.
+- *Batch* support defaults to calling the underlying ChatModel in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
+
+Each ChatModel integration can optionally provide native implementations to truly enable async or streaming.
+The table shows, for each integration, which features have been implemented with native support.

-# Chat loaders
-
-Like document loaders, chat loaders are utilities designed to help load conversations from popular communication platforms such as Facebook, Slack, Discord, etc. These are loaded into memory as LangChain chat message objects. Such utilities facilitate tasks such as fine-tuning a language model to match your personal style or voice. 
-
-This brief guide will illustrate the process using [OpenAI's fine-tuning API](https://platform.openai.com/docs/guides/fine-tuning) comprised of six steps:
-
-1. Export your Facebook Messenger chat data in a compatible format for your intended chat loader.
-2. Load the chat data into memory as LangChain chat message objects. (_this is what is covered in each integration notebook in this section of the documentation_).
-    - Assign a person to the "AI" role and optionally filter, group, and merge messages.
-3. Export these acquired messages in a format expected by the fine-tuning API.
-4. Upload this data to OpenAI.
-5. Fine-tune your model.
-6. Implement the fine-tuned model in LangChain.
-
-This guide is not wholly comprehensive but is designed to take you through the fundamentals of going from raw data to fine-tuned model.
-
-We will demonstrate the procedure through an example of fine-tuning a `gpt-3.5-turbo` model on Facebook Messenger data. 
-
-### 1. Export your chat data
-
-To export your Facebook messenger data, you can follow the [instructions here](https://www.zapptales.com/en/download-facebook-messenger-chat-history-how-to/). 
-
-:::important JSON format
-You must select "JSON format" (instead of HTML) when exporting your data to be compatible with the current loader.
-:::
-
-OpenAI requires at least 10 examples to fine-tune your model, but they recommend between 50-100 for more optimal results.
-You can use the example data stored at [this google drive link](https://drive.google.com/file/d/1rh1s1o2i7B-Sk1v9o8KNgivLVGwJ-osV/view?usp=sharing) to test the process.
-
-### 2. Load the chat
-
-Once you've obtained your chat data, you can load it into memory as LangChain chat message objects. Here’s an example of loading data using the Python code:
-
-```python
-from langchain.chat_loaders.facebook_messenger import FolderFacebookMessengerChatLoader
-
-loader = FolderFacebookMessengerChatLoader(
-    path="./facebook_messenger_chats",
-)
-
-chat_sessions = loader.load()
-```
-
-In this snippet, we point the loader to a directory of Facebook chat dumps which are then loaded as multiple "sessions" of messages, one session per conversation file.
-
-Once you've loaded the messages, you should decide which person you want to fine-tune the model to (usually yourself). You can also decide to merge consecutive messages from the same sender into a single chat message.
-For both of these tasks, you can use the chat_loaders utilities to do so:
-
-```
-from langchain.chat_loaders.utils import (
-    merge_chat_runs,
-    map_ai_messages,
-)
-
-merged_sessions = merge_chat_runs(chat_sessions)
-alternating_sessions = list(map_ai_messages(merged_sessions, "My Name"))
-```
-
-### 3. Export messages to OpenAI format
-
-Convert the chat messages to dictionaries using the `convert_messages_for_finetuning` function. Then, group the data into chunks for better context modeling and overlap management.
-
-```python
-from langchain.adapters.openai import convert_messages_for_finetuning
-
-openai_messages = convert_messages_for_finetuning(chat_sessions)
-```
-
-At this point, the data is ready for upload to OpenAI. You can choose to split up conversations into smaller chunks for training if you
-do not have enough conversations to train on. Feel free to play around with different chunk sizes or with adding system messages to the fine-tuning data.
-
-```python
-chunk_size = 8
-overlap = 2
-
-message_groups = [
-    conversation_messages[i: i + chunk_size] 
-    for conversation_messages in openai_messages
-    for i in range(
-        0, len(conversation_messages) - chunk_size + 1, 
-        chunk_size - overlap)
-]
-
-len(message_groups)
-# 9
-```
-
-### 4. Upload the data to OpenAI
-
-Ensure you have set your OpenAI API key by following these [instructions](https://platform.openai.com/account/api-keys), then upload the training file.
-An audit is performed to ensure data compliance, so you may have to wait a few minutes for the dataset to become ready for use.
-
-```python
-import time
-import json
-import io
-
-import openai
-
-my_file = io.BytesIO()
-for group in message_groups:
-    my_file.write((json.dumps({"messages": group}) + "\n").encode('utf-8'))
-
-my_file.seek(0)
-training_file = openai.File.create(
-  file=my_file,
-  purpose='fine-tune'
-)
-
-# Wait while the file is processed
-status = openai.File.retrieve(training_file.id).status
-start_time = time.time()
-while status != "processed":
-    print(f"Status=[{status}]... {time.time() - start_time:.2f}s", end="\r", flush=True)
-    time.sleep(5)
-    status = openai.File.retrieve(training_file.id).status
-print(f"File {training_file.id} ready after {time.time() - start_time:.2f} seconds.")
-```
-
-Once this is done, you can proceed to the model training!
-
-### 5. Fine-tune the model
-
-Start the fine-tuning job with your chosen base model.
-
-```python
-job = openai.FineTuningJob.create(
-    training_file=training_file.id,
-    model="gpt-3.5-turbo",
-)
-```
-
-This might take a while. Check the status with `openai.FineTuningJob.retrieve(job.id).status` and wait for it to report `succeeded`.
-
-```python
-# It may take 10-20+ minutes to complete training.
-status = openai.FineTuningJob.retrieve(job.id).status
-start_time = time.time()
-while status != "succeeded":
-    print(f"Status=[{status}]... {time.time() - start_time:.2f}s", end="\r", flush=True)
-    time.sleep(5)
-    job = openai.FineTuningJob.retrieve(job.id)
-    status = job.status
-```
-
-### 6. Use the model in LangChain
-
-You're almost there! Use the fine-tuned model in LangChain.
-
-```python
-from langchain import chat_models
-
-model_name = job.fine_tuned_model
-# Example: ft:gpt-3.5-turbo-0613:personal::5mty86jblapsed
-model = chat_models.ChatOpenAI(model=model_name)
-```
-
-```python
-from langchain.prompts import ChatPromptTemplate
-from langchain.schema.output_parser import StrOutputParser 
-
-prompt = ChatPromptTemplate.from_messages(
-    [
-        ("human", "{input}"),
-    ]
-)
-
-chain = prompt | model | StrOutputParser()
-
-for tok in chain.stream({"input": "What classes are you taking?"}):
-    print(tok, end="", flush=True)
-
-# The usual - Potions, Transfiguration, Defense Against the Dark Arts. What about you?
-```
-
-And that's it! You've successfully fine-tuned a model and used it in LangChain.
-
-## Supported Chat Loaders
-
-LangChain currently supports the following chat loaders. Feel free to contribute more!
