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.
