O narzędziu
LangChain is the most widely adopted open-source framework for building LLM-powered applications, providing abstractions for chains, agents, memory, and retrieval-augmented generation (RAG). It supports over 100 LLM providers and vector stores, and has a massive ecosystem of community integrations. LangGraph extends it with stateful, graph-based agent orchestration for complex multi-step workflows. LangSmith provides observability, testing, and evaluation for production deployments.
