    From the README

    LangChain is a framework for building LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development — all while future-proofing decisions as the underlying technology evolves.

    Documentation: To learn more about LangChain, check out the docs.

    If you're looking for more advanced customization or agent orchestration, check out LangGraph, our framework for building controllable agent workflows.

    LangChain helps developers build applications powered by LLMs through a standard interface for models, embeddings, vector stores, and more.

    While the LangChain framework can be used standalone, it also integrates seamlessly with any LangChain product, giving developers a full suite of tools when building LLM applications.
