autotrust/JEV-9B

An open student of Jev 1.13 with System 1 and System 2 in one set of weights.

AutoTrust keeps Qwen3.5-9B frozen and adds a small, detachable expert block for typed decisions, so one vLLM engine serves both calibrated System 1 answers and ordinary reasoning. On 25,376 held-out questions labelled with Jev 1.13's own distributions, the mean KL divergence is about 0.019. A 27B successor is also on Hugging Face.
