Jev is TypeSafe AI's first System One model, launched in early access on September 15, 2026. It is not a chatbot: you send unstructured or structured state plus typed questions and get structured answers your code can branch on. The documented model alias is jev-latest on POST https://api.typesafe.ai/v1/systemone. Question primitives are Choice (up to 255 options), Score, and Noul (yes/no probability). TypeSafe lists $0.042 per million input tokens with output tokens unmetered, and 70–500 ms end-to-end on its launch workloads. Training is Reinforcement Learning for Calibrated Decisions (RLCD).
