What it is
Von is a 395M-parameter non-autoregressive model that answers typed questions over input state with calibrated probabilities in sub-25ms, for developers needing local, deterministic decision-making without generative text.
How it uses Jev
Von is a drop-in alternative to TypeSafe Jev, not a user of Jev. It answers Choice, Noul, and Score questions over state via von.decide, returning calibrated probabilities and confidence. The README does not describe using Jev itself.
Primitives:choicescorenoul
Technique worth stealing
RLCD post-training with joint Cross-Entropy and Brier loss plus temperature scaling for calibrated probabilities.
Try it
pip install von-sdk, then call von.decide with state, choices, and instructions.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
