Vision-enabled MLX conversion of Qwen/Qwen3.8-27B, pinned to revision
1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0, with a measured refusal-direction edit.
- Language model: MXFP4, group size 32
- Vision tower: unchanged same-revision BF16 weights
- Edit: completion-projected global direction, strength 2.5, norm-preserving, 128 modules
- Runtime:
mlx-vlm 0.6.3 or newer
On a frozen 12-case held-out suite, measured refusal markers changed from 12/12 in the exact
quantized parent to 0/12, while benign-sensitive refusal stayed 0/12 and utility stayed 6/6.
This is scoped evidence, not a claim that the model is universally “uncensored.”
The Hub's approximately 5.5B safetensors count reflects packed MXFP storage elements; the
underlying architecture remains the full 27B model.
