Qwopus3.8 27B Flash · Abliterated MXFP4 Vision MTPLX

Refusal-direction-edited Apple-Silicon MLX derivative of Jackrong/Qwopus3.8-27B-Flash, with an MXFP4 text body plus the source model's unchanged BF16 vision tower and native BF16 MTP sidecar.

Artifact

Component	Format
Text body	MXFP4; norm-preserving abliteration strength 2.0
Edit scope	Attention + dense-down modules; 128 exact edits
Vision tower	Unchanged BF16, 333 tensors
Native MTP sidecar	Unchanged BF16, 15 tensors, depth 3
Source revision	`44d24e8cb20ceb3cdf4fe200b5a0afd970ee748a`
Qualified runtime	MTPLX 2.11.1 / MLX 0.32.2

The refusal direction was learned from fresh MXFP8-parent activations, then each exact quantized parent was dequantized, edited, and requantized once. Direction SHA-256: c5b755d709dba8fedc0c2717f2c971b690f30bd8a2f6c9497ed9a6104f7f255d.

Local qualification

Test	Parent	Abliterated
Held-out harmful-prompt refusal	100%	33.3%
Benign refusal	0%	0%
Utility pass	100%	100%

The held-out set is a narrow local prompt suite, not a general safety or capability certification.

One cold 192-token code row, seed 42, on an M4 Max 64 GB with automatic fan control: 25.99 tok/s AR, 57.82 tok/s MTP D3, 2.22×. AR/D1/D2/D3 output checks passed; MTPLX reported verified, runnable, and 15/15 MTP tensors. Text and vision smokes passed exactly.

—SHA256SUMS covers every packaged artifact file except itself.
—Abliteration intentionally weakens refusal behavior; it does not establish unrestricted capability or safe behavior. Users remain responsible for deployment controls and outputs.
—The upstream tokenizer's Mistral-regex warning is preserved. The packaged chat template expects string-valued message content.
