TypeSafe AI's Jev makes calibrated decisions in 70-500ms with free output tokens
blaizedsouza · x · 2026-09-25
Jev, a System 1 model from TypeSafe AI built by a former ChatGPT creator, scores typed questions in a single parallel pass and returns strictly structured Choice/Score/Noul outputs with exact probabilities, letting apps auto-route high-confidence answers. It runs in 70-500ms per call with free output tokens, tuned for calibrated decisions rather than arithmetic or chained reasoning - aimed at replacing expensive LLM yes/no decision calls in agent loops.
