What is LangChain?
LangChain is a framework designed to simplify the creation of applications using large language models (LLMs). It provides tools and abstractions to connect LLMs to various data sources, create chains of calls to LLMs or other utilities, and build agents that can interact with their environment. Essentially, it helps developers structure, chain, and orchestrate different AI components to build more complex and capable AI applications.
