Jev is TypeSafe AI's System One model: it turns messy input into typed, calibrated decisions software can use directly — no hallucinations, 70–500ms. Try it free in the browser and learn the API.

Jev = fast, typed decisions for AI agents and software — choice, score, or yes/no probability, in 70–500ms. Four ways to feel a decision model — the simplest play, a real tool, the agent loop, and a game. You hand Jev the context and the questions. No — Jev is a hosted model from TypeSafe AI, called over an API. Three routes: official TypeSafe access, a gateway (Vercel AI Gateway, OpenRouter or Cloudflare), or an instant hosted key from us.
