## Overview

LangGraph is a low-level framework for stateful agents, with Python and JavaScript implementations. Developers define shared state, processing nodes and transition conditions, combining deterministic code with model decisions in one graph. Checkpoints and persistence save progress and support resumed execution; human review can inspect or change state at key steps. Models, tools and hosting must be supplied separately: this is a development framework rather than a ready-to-use chat application.
