LangGraph SDK

The LangGraph SDK (langgraph-sdk) is a Python client for interacting with the LangGraph API (also known as LangSmith Deployment REST API), allowing programmatic access to manage Assistants, Threads, Runs, and Cron jobs. Currently at version 0.3.12, it provides both synchronous and asynchronous clients, serving as a key interface for deploying and managing stateful AI agents orchestrated by the LangGraph framework. The library is part of the actively developed LangChain ecosystem.
