Description

LangChain is a widely adopted "LLM application framework" offering powerful "API tools for building context-aware applications" powered by large language models (LLMs).

It is essential for AI developers creating intelligent, complex applications beyond simple LLM prompts.

Key features include "agents" (LLMs that reason and perform actions), "chains" (sequences of LLM calls and components), and "memory" for maintaining conversational context.

It also provides over "80 document loaders" for data integration and numerous "toolkits" for interfacing with external systems.

LangChain’s modular components and structured approach simplify development of advanced LLM applications, enabling chatbots, analysis tools, and intelligent systems leveraging external knowledge and APIs.
