# ⚡ Flash Diffusion: FlashSD3 ⚡
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* from Jasper Research.
This model is a **90.4M** LoRA distilled version of [SD3](https://huggingface.co/stabilityai/stable-diffusion-3-medium) model that is able to generate 1024x1024 images in **4 steps**.
See our [live demo](https://huggingface.co/spaces/jasperai/flash-sd3) and official [Github repo](https://github.com/gojasper/flash-diffusion).

# How to use?
The model can be used using the `StableDiffusion3Pipeline` from `diffusers` library directly. It can allow reducing the number of required sampling steps to **4 steps**.
⚠️ First, you need to install a specific version of `diffusers` by running ⚠️
```bash
pip install git+https://github.com/initml/diffusers.git@clement/feature/flash_sd3
```
Then, you can run the following to generate an image
```python
import torch
from diffusers import StableDiffusion3Pipeline, SD3Transformer2DModel, FlashFlowMatchEulerDiscreteScheduler
from peft import PeftModel
# Load LoRA
transformer = SD3Transformer2DModel.from_pretrained(
"stabilityai/stable-diffusion-3-medium-diffusers",
subfolder="transformer",
torch_dtype=torch.float16,
)
transformer = PeftModel.from_pretrained(transformer, "jasperai/flash-sd3")
# Pipeline
pipe = StableDiffusion3Pipeline.from_pretrained(
"stabilityai/stable-diffusion-3-medium-diffusers",
transformer=transformer,
torch_dtype=torch.float16,
text_encoder_3=None,
tokenizer_3=None
)
# Scheduler
pipe.scheduler = FlashFlowMatchEulerDiscreteScheduler.from_pretrained(
"stabilityai/stable-diffusion-3-medium-diffusers",
subfolder="scheduler",
)
pipe.to("cuda")
prompt = "A raccoon trapped inside a glass jar full of colorful candies, the background is steamy with vivid colors."
image = pipe(prompt, num_inference_steps=4, guidance_scale=0).images[0]
```

## Training details
The model was trained for ~50 hours on 2 H100 GPUs.
💡 Training Hint : Model could perform much better on text if distilled on dataset of images containing text, feel free to try it yourself.
