A framework for building applications powered by large language models (LLMs).
The 2022 framework that named the category: chains, retrievers, agents and integrations for LLM apps. Criticized for abstraction bloat, still enormous by adoption and now split into leaner langchain-core with LangGraph for stateful orchestration. The Swiss-army knife that seeded the ecosystem.
Who it's for
Developers prototyping LLM apps who want the widest choice of integrations, chains and tooling.
