Jev 1.13
The first System One model. Reads a state, answers typed Choice, Score and Noul questions in one call with calibrated probabilities, and generates no text. Closed weights, served by TypeSafe AI.
Jev is served as a hosted API only; no weights, parameter count or paper have been published. Each request carries a state of up to 32k tokens and a set of questions answered in parallel: Choice over up to 255 options, Score over 2 to 10 levels, and Noul, a yes/no probability. TypeSafe quotes 70–500 ms per request; third-party measurements put the median at 236–276 ms. Pricing is $0.042 per million input tokens, with output free. The waitlist was removed on 20 September 2026.
What it decides
- choice — picks one option from a set
- score — places the input on an ordered scale
- noul — answers a yes/no question with one calibrated probability
- classify — assigns a category from a fixed taxonomy
- route — sends the input to one of several destinations
