This repository contains multiple packages:
- `langchain-core`: Base interfaces for key abstractions as well as logic for combining them in chains (LangChain Expression Language).
- `langchain-community`: Third-party integrations of various components.
- `langchain`: Chains, agents, and retrieval logic that makes up the cognitive architecture of your applications.
- `langchain-experimental`: Components and chains that are experimental, either in the sense that the techniques are novel and still being tested, or they require giving the LLM more access than would be possible in most production systems.
- Partner integrations: Partner packages in `libs/partners` that are independently version controlled.
:::note
Some LangChain packages live outside the monorepo, see for example
[langchain-community](https://github.com/langchain-ai/langchain-community) for various
third-party integrations and
[langchain-experimental](https://github.com/langchain-ai/langchain-experimental) for
abstractions that are experimental (either in the sense that the techniques are novel
and still being tested, or they require giving the LLM more access than would be
possible in most production systems).

Each of these has its own development environment. Docs are run from the top-level makefile, but development
is split across separate test & release flows.
