The emphasis is on multi-step orchestration and context handling, which is where AI products start becoming executable workflow systems.

From the source

Production agents fail in ways prototypes never do. This post walks through the three fault tolerance primitives built into LangGraph: RetryPolicy for automatic retries with backoff, TimeoutPolicy for wall-clock and idle-based caps, and error_handler for cleanup logic once retries are exhausted. Learn how they

Why open it
