LangChain
AI 에이전트An 오픈소스 프레임워크 for building AI 에이전트 powered by LLMs. Features extensive 연동s and multi-agent support via LangGraph.
LangChain이란?
LangChain is an 오픈소스 프레임워크 for building applications and AI 에이전트 powered by 대규모 언어 모델s (LLMs). With over 118,000 GitHub stars, it is the world's largest LLM 프레임워크, supporting 연동 major LLM providers including OpenAI, Anthropic, and Google AI. It comprehensively provides the functionality needed for AI 에이전트 construction: 프롬프트 chaining, memory management, tool calling, and RAG (Retrieval-Augmented Generation). The LangGraph companion project enables building stateful multi-agent applications. LangSmith (paid) streamlines agent monitoring, evaluation, and 디버깅.
