LangGraph taps Jev as a cheap, fast classifier to add control-flow primitives to agent flows

Harrison Chase boosts an article on building a harness with Jev: Jev is a very good, cheap, fast classifier, and incorporating it lets you use more workflow, DAG and control-flow primitives in your agent flows. The article describes the core agent loop: an LLM decides what to do, a tool executes, a model evaluates the results, and the loop continues until the task is complete.
