LangGraph

LangGraph is a framework from LangChain for building and running stateful AI agents. Its official documentation explains concepts such as graph-based execution, durable workflows and coordinating model calls with tools and application state.

The framework is intended for developers building their own agent systems and can be used independently of higher-level LangChain abstractions. Start with the documented setup and examples for the chosen language, then evaluate the actual workflow and deployment requirements of the application.
