LangChain describes how LangGraph orchestrates TypeSafe AI's Jev, a model that returns structured decisions rather than text, for production agent workflows. TypeSafe benchmarks report Jev running up to 200x faster and 400x cheaper than leading LLMs on routing and classification.

The 'code owns workflow, AI handles narrow decisions' split is a useful architectural pattern for agent builders, and the post shows how LangGraph wires it together.
