LangGraph: Build Durable, Stateful AI Agents in Python
A practical guide to LangGraph, the durable agent framework that hit 1.0 in October 2025 and the 1.2 line by mid-2026. It covers the three core primitives (state, nodes, edges), conditional edges for branching and loops, and checkpointer-based persistence for crash recovery and memory. It also explains the deprecation of create_react_agent in favor of LangChain's create_agent, and the rule of thumb for choosing between the high-level agent builder and low-level StateGraph.
