A Jevify Tier 2 model: Qwen/Qwen3-VL-2B-Instruct used as a vision-language model: state may carry images (PIL, path, URL, data URI or bytes) and the same three typed questions are asked about them, with a rank-16 LoRA confined to the decoder half of the model, trained on the readout itself — the restricted log-softmax over the allowed answers at the answer position — with the primitive's proper scoring rule, on the aokvqa train split only. The adapter (17,432,576 parameters) is merged into the backbone at load, so it serves at the plain checkpoint's speed. The calibration recipe was fitted on validation splits of the adapted model. pope, ai2d never appeared in training. Serve it as a…

A System One decision model: it does not write text. It reads a state, answers typed questions (choice, score, noul), and returns calibrated probability distributions your code can branch on. This repo is a rank-16 LoRA (34,881,536 parameters) on google/gemma-4-E4B-it, merged into the weights at load. How it was trained (readout fine-tuning). The model is trained on its own decision readout — the distribution over the allowed answers read at the answer position, one forward pass, no decoding — with the primitive's proper scoring rule, plus a coherence penalty (weight 1.0): every training question comes with automatically derived siblings (the options as yes/no questions, the negation, the…

The model is trained on its own decision readout — the distribution over the allowed answers read at the answer position, one forward pass, no decoding — with the primitive's proper scoring rule. Options are shuffled per family. Training data: the train splits of the 16 non-held-out jev-bench sources (5,885 families, at most 400 records per source); lr…

Real human-labeled data, reformatted into System One questions — with human label distributions wherever they exist. 22 configs · 166,054 rows · 22,773 on the same 22,773 test records. Down and to the right is better; the stars are open models fine-tuned on their own decision readout with a coherence penalty. Contents — model (TypeSafe's Jev, or any open model Jevified by the engine) does not write text. It reads a state, answers typed questions, and returns probability distributions your code can branch on. The product claim is calibration: an answer given 0.8 should be right about 80% of the time. Most benchmarks can only check the argmax; jev-bench checks the distribution — four configs…
