Jev

Jev is TypeSafe AI's 'System One' frontier model designed for software automation. Rather than generating free-form text, it takes unstructured input state and returns typed, probabilistic decisions — Choice, Score, and Noul answers with calibrated probabilities that code can act on directly. Parallel sampling delivers response times of roughly 70–500ms, which the vendor states is about 20–200x faster and 40–400x cheaper than comparable LLM workflows, with output tokens free. Jev is available via console.typesafe.ai with no waitlist.
