## What is LangChain?

LangChain is an open-source framework and developer toolkit for building LLM-powered apps. The library provides retrieval augmented generation tools, LLM agents, and the ability to chain together calls to LangChain components — all of which empower developers to build and ship generative AI applications.

## See how an LLM “thinks”

- Read the “mind” of an LLM
- Generate a blog outline
- Summarize text
