Qwen-Image Full Distillation Accelerated Model

[image]

Model Introduction

This model is a distilled and accelerated version of Qwen-Image. The original model requires 40 inference steps and uses classifier-free guidance (CFG), resulting in a total of 80 forward passes. The distilled accelerated model only requires 15 inference steps and does not need CFG, resulting in only 15 forward passes — achieving about 5× speed-up. Of course, the number of inference steps can be further reduced if needed, but generation quality may decrease.

The training framework is built using DiffSynth-Studio. The training dataset consists of 16,000 images generated by the original model using randomly sampled prompts from DiffusionDB. Training was conducted for about 1 day on 8 × MI308X GPUs.
