LangGraph Released: A New Paradigm for Building Stateful Agents

The LangChain team has released LangGraph, which models agent workflows as directed graphs (DAGs), supporting cyclic execution, persistent state, and human-in-the-loop nodes. Compared to LangChain Agents, LangGraph offers significantly improved controllability and debuggability, making it the preferred framework for production-level agent development, with over 9,000 GitHub stars.
