# ⚡ Flash Diffusion: FlashSDXL ⚡
Flash Diffusion is a diffusion distillation method proposed in [Flash Diffusion: Accelerating Any Conditional
Diffusion Model for Few Steps Image Generation](http://arxiv.org/abs/2406.02347) *by Clément Chadebec, Onur Tasar, Eyal Benaroche, and Benjamin Aubin.*
This model is a **108M** LoRA distilled version of [SDXL](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) model that is able to generate images in **4 steps**. The main purpose of this model is to reproduce the main results of the paper.
See our [live demo](https://huggingface.co/spaces/jasperai/FlashPixart) and [official implementation](https://github.com/gojasper/flash-diffusion).

# How to use?
The model can be used using the `DiffusionPipeline` from `diffusers` library directly. It can allow reducing the number of required sampling steps to **4 steps**.
```python
from diffusers import DiffusionPipeline, LCMScheduler
adapter_id = "jasperai/flash-sdxl"
pipe = DiffusionPipeline.from_pretrained(
"stabilityai/stable-diffusion-xl-base-1.0",
use_safetensors=True,
)
pipe.scheduler = LCMScheduler.from_pretrained(
"stabilityai/stable-diffusion-xl-base-1.0",
subfolder="scheduler",
timestep_spacing="trailing",
)
pipe.to("cuda")
# Fuse and load LoRA weights
pipe.load_lora_weights(adapter_id)
pipe.fuse_lora()
prompt = "A raccoon reading a book in a lush forest."
image = pipe(prompt, num_inference_steps=4, guidance_scale=0).images[0]
```

# Training Details
The model was trained for 20k iterations on 4 H100 GPUs (representing approximately a total of 176 GPU hours of training). Please refer to the [paper](http://arxiv.org/abs/2406.02347) for further parameters details.
**Metrics on COCO 2014 validation (Table 3)**
- FID-10k: 21.62 (4 NFE)
- CLIP Score: 0.327 (4 NFE)
