What LangGraph does
LangGraph is a low-level orchestration framework and runtime for building, managing and deploying long-running, stateful AI agents, built by LangChain. It is for developers who want fine-grained control over agent behavior rather than a higher-level agent abstraction, and it can be used without LangChain itself. LangGraph lets teams mix hand-coded, deterministic steps with LLM-driven steps in a single graph. Named features include persistence so agents can resume after failures, human-in-the-loop oversight with the ability to inspect and modify state, and short-term and long-term memory. Debugging and tracing run through LangSmith, and production deployment is available through LangSmith Deployment. The documentation lists it as part of the open source stack.
