Qwen-Image-Distill-LoRA

Qwen-Image LoRA Distillation Acceleration Model

Model Introduction

This model is a distilled and accelerated LoRA version of Qwen-Image. We follow the same training procedure as used in DiffSynth-Studio/Qwen-Image-Distill-Full, but replace the trainable model parameters with LoRA, making it easier to integrate into various image generation frameworks.

The training framework is built on DiffSynth-Studio. The training data consists of 16,000 images generated by the original model using randomly sampled prompts from DiffusionDB. The training process ran for approximately one day on 8 * MI308X GPUs.
