Qwopus3.8 27B Flash · MXFP4 Vision MTPLX
Apple-Silicon MLX release of Jackrong/Qwopus3.8-27B-Flash: an MXFP4 text body paired with the source model's exact BF16 vision tower and exact native BF16 MTP sidecar.
Artifact
| Component | Format |
|---|---|
| Text body | MXFP4 |
| Vision tower | BF16, 333 tensors |
| Native MTP sidecar | BF16, 15 tensors, depth 3 |
| Source revision | 44d24e8cb20ceb3cdf4fe200b5a0afd970ee748a |
| Qualified runtime | MTPLX 2.11.1 / MLX 0.32.2 |
The conversion used the pinned BF16 safetensors source—not a requantization of the GGUF release.

This starts the local OpenAI-compatible endpoint. The packaged tokenizer, processor, vision weights, chat template, and MTP runtime contract are included.
Local qualification
One cold 192-token code row, seed 42, on an M4 Max 64 GB with automatic fan control:
| AR | MTP D3 | D3 / AR |
|---|---|---|
| 26.43 tok/s | 56.74 tok/s | 2.15× |
AR/D1/D2/D3 output checks passed. MTPLX inspection reported verified, runnable, and 15/15 MTP tensors. Strict text load returned the expected 42; vision identified the test shape/color exactly. These are narrow local qualification results, not a cross-hardware benchmark.
