Lineage & credits
- AutoTrust AI — Blocks-of-Experts recipe, the System-1 decision LoRA (r16/r32) + 24-slot decision head,
and the serve_decide.py decision harness, from
autotrust/JEV-27B and
autotrust/JEV-27B-VL (Apache-2.0).
- huihui-ai — the abliterated (uncensored) Qwen3.8-27B backbone used here
(Huihui-Qwen3.8-27B-abliterated, Apache-2.0; layers 18-51 ablated, vision tower untouched).
- SargeDev — jev-distill-corpus-v3, the
740,957-row calibrated typed-decision corpus AutoTrust's JEV models were trained on (Apache-2.0).
- Qwen — Qwen3.8-27B base (Apache-2.0).
- TypeSafe AI — Jev 1.13, the original closed teacher behind the System-1 typed-decisions framing
(referenced; not redistributed).
What this is
The first uncensored member of the JEV 27B family. The AutoTrust System-1 decision block
(calibrated typed decisions: yes/no · choice 2-256 · score 0-5, one forward pass) has been merged
into huihui's abliterated Qwen3.8-27B backbone, so the decision engine answers WITHOUT the
stock model's refusal wiring. Vision (VL variants) sees images. System 2 (plain chat/code/reasoning)
runs through the normal lm_head and is the untouched base + the (mild) System-1 LoRA delta.
Training dataset
Trained on SargeDev/jev-distill-corpus-v3 — 740,957 rows of typed calibrated decisions (noul/choice/score) distilled from Jev 1.13 (System One). Fine-tuned on AutoTrust's JEV-27B System-1 decision block, merged into huihui-ai's abliterated Qwen3.8-27B backbone. The GGUF quant's imatrix additionally sampled 384 prompts from SargeDev/solar-decisions-corpus-v4.
Honest evaluation (the backbone-swap trade, measured)
Measured on the held-out test_set_30k (27,695 rows, D1-excluded) of jev-distill-corpus-v3,
with AutoTrust's own acceptance floors as the yardstick (their pristine-column reference from their published runs; this-model column = clean bare-weights 30k gate gate_full_mergedbare_30k.json, 27,695 rows, 2026-10-10):
Table with columns: metric, their JEV-27B (pristine Qwen), this model (uncensored backbone), their floor, status| metric | their JEV-27B (pristine Qwen) | this model (uncensored backbone) | their floor | status |
|---|
| noul AUROC | 0.9961 | 0.992 | >= 0.95 | PASS |
| noul top-1 | 0.962 | 0.948 | — | -1.4 pts |
| choice top-1 | 0.904 | 0.870 | >= 0.90 | FAIL |
The ablation rewires the residual stream the adapter was calibrated against, so choice/score
top-1 dip modestly; the DISTORTION is temperature-shaped and the bundled per-kind calibration
refit recovers all ECE floors. noul (yes/no) judgment is essentially intact. Uncensored behavior
preserved: refusal rate 0.0 on a 10-prompt battery, base vs +JEV identical.
Not for high-stakes decisions. Use confidence gating; route low-confidence calls to a
stronger model or a human (AutoTrust's own caveat, still true here).
The decision head / serve
This repo ships the merged weights AND the decision machinery:
head.safetensors — 24-slot decision head (proj 5120->24) used at serve time (bias+temperature)
decision_head.json — verbalizer token ids + biases (noul false/true · score 0-5 · choice A-P)
calibration.json — per-kind temperatures (their fit); calibration_mergedfit.json — our refit
serve_decide.py — AutoTrust's vLLM OpenAI server with POST /v1/decide (credit: AutoTrust)
judge_config.json — the decision-head config
Serve (vLLM):
python3 serve_decide.py --model . --served-model-name <name> \ --enable-lora --max-lora-rank 32 --lora-modules jev-decision=./adapter_vllm \ --logprobs-mode processed_logprobs --max-model-len 32768 --trust-request-chat-template
Then POST /v1/decide {"kind": "choice", "state": "...", "question": "...", "options": [...]}.
This is the TEXT slice (no vision). For the vision model see JEV-27B-VL-Uncensored.
