mflux 6bit quantization of Qwen-Image-2.1

An Osaurus 6bit mflux quantization of Qwen/Qwen-Image-2.1 for Apple Silicon (14 GB, balanced size and quality). This is not an official Qwen release and is not endorsed by the Qwen team.

One bundle does both text-to-image and reference editing (up to 10 ordered reference images); the vision encoder is included.

Changes from the original (LICENSE §3(b))

• Transformer and text/vision encoder weights re-saved with mflux and quantized to MLX affine 6-bit, group size 64 (modulation, timestep embedding and output norm kept in bf16).
• VAE re-saved in fp32, unquantized.
• No fine-tuning or other change to the model.

Generated images

The Qwen team has stated that "Outputs are not part of the licensed Materials. Users retain the rights to images and other content they generate using the model." This does not grant commercial use of the model itself; running the model remains limited to research and evaluation unless you hold a commercial license.

Use in Osaurus

Download it from the Image models tab, then generate or edit from chat or the image panel. Defaults: 40 steps, guidance 1.0, sizes in multiples of 32.
