LangChain

LangChain is a powerful open-source framework designed to simplify the development of applications powered by large language models (LLMs). It provides a complete set of interoperable building blocks for creating context-aware, reasoning applications with vendor optionality. LangChain connects LLMs to company data and APIs, enabling rapid prototyping to production deployment with methods like RAG, agents, and complex orchestration workflows.
