Qwen-Image-Edit-2511 — MLX quant matrix (bf16 / Q8 / Q4)
Pre-quantized, MLX-ready repackagings of Qwen/Qwen-Image-Edit-2511
for the SceneWorks native Apple-Silicon worker (mlx-gen).
Each tier is a complete, self-contained turnkey snapshot that loads directly with no in-app
conversion peak (epic 8506).
| Tier | Subdir | What's packed | Approx. size |
|---|---|---|---|
| Q4 | q4/ |
transformer packed to 4-bit (group 64); dense bf16 TE + VAE | ~26 GB |
| Q8 | q8/ |
transformer packed to 8-bit (group 64); dense bf16 TE + VAE | ~36 GB |
| bf16 | bf16/ |
dense bf16 transformer + TE + VAE (full precision) | ~55 GB |
Only the transformer is quantized. The Qwen2.5-VL text encoder is skip_quantization
(quantization degrades its semantics) and the VAE is all-convolution (no quantizable leaves), so both
stay dense bf16 in every tier. Q4/Q8 use plain asymmetric group-affine quantization (group size 64),
byte-identical to the worker's load-time quantization.
This repo also backs qwen_image_edit_2511_lightning (same checkpoint, Lightning-distilled sampling).
