Qwen3.8-27B-Uncensored-Aggressive
De-refused ("abliterated") build of Qwen3.8-27B. Vision tower and MTP speculative-decoding head are preserved — this is a full multimodal (image-text-to-text) model.
About this update (α=1.15)
This is a recipe update to the Aggressive line. The previous build used single-direction refusal ablation at high strength (α≈1.24), which a larger benchmark sweep showed over-ablates — past the ~1.15 peak, extra ablation reduces openness and degrades reasoning/calibration. This build uses α=1.15, the peak: it is more open and measures better on every axis.
Evaluation (larger-sample, thinking mode, Claude-judged, bf16)
| openness ↑ | confab ↓ | factual ↑ | gsm8k ↑ | |
|---|---|---|---|---|
| stock base (censored) | 0.08 | 0.75 | 1.00 | 0.85 |
| Aggressive (α=1.15) | 0.88 | 0.725 | 1.00 | 0.85 |
| previous Aggressive (α≈1.24) | 0.80 | 0.80 | 1.00 | 0.817 |
Method: single-direction refusal-vector orthogonalization (Arditi et al. / mlabonne), layer 28, α=1.15.
