Summary
A deep-dive overview of Jev, TypeSafe's System One model, describing it as a fast, typed decision engine that returns structured outputs (noul, choice, score) rather than free-form text. The piece compares Jev to ChatGPT and coding agents, explains how to use it across languages and SDKs, and outlines use cases, patterns (speculative fan-out, composite scoring, intent routing), costs, and rollout strategies.
