LangChain

LLM framework

LangChain is one of the most widely used open-source frameworks for LLM applications, with integrations for almost every model provider, vector database and tool. Since version 1.0 its agent functionality is built on LangGraph. The many abstractions make getting started demanding, even for experienced developers.
