# Qwen-Image LoRA Distillation Acceleration Model
## Model Introduction
This model is a distilled and accelerated LoRA version of [Qwen-Image](https://www.modelscope.cn/models/Qwen/Qwen-Image). We follow the same training procedure as used in [DiffSynth-Studio/Qwen-Image-Distill-Full](https://modelscope.cn/models/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](https://github.com/modelscope/DiffSynth-Studio). The training data consists of 16,000 images generated by the original model using randomly sampled prompts from [DiffusionDB](https://www.modelscope.cn/datasets/AI-ModelScope/diffusiondb). The training process ran for approximately one day on 8 * MI308X GPUs.

## Inference Code
```shell
git clone https://github.com/modelscope/DiffSynth-Studio.git
cd DiffSynth-Studio
pip install -e .
```
```python
from diffsynth.pipelines.qwen_image import QwenImagePipeline, ModelConfig
from modelscope import snapshot_download
import torch
snapshot_download("DiffSynth-Studio/Qwen-Image-Distill-LoRA", local_dir="models/DiffSynth-Studio/Qwen-Image-Distill-LoRA")
pipe = QwenImagePipeline.from_pretrained(
torch_dtype=torch.bfloat16,
device="cuda",

)
pipe.load_lora(pipe.dit, "models/DiffSynth-Studio/Qwen-Image-Distill-LoRA/model.safetensors")
prompt = "Exquisite portrait, underwater girl, flowing blue dress, gently floating hair, translucent lighting, surrounded by bubbles, serene expression, intricate details, dreamy and ethereal."
image = pipe(prompt, seed=0, num_inference_steps=15, cfg_scale=1)
