⚡ Flash Diffusion: FlashSD ⚡
Flash Diffusion is a diffusion distillation method proposed in ADD ARXIV by Clément Chadebec, Onur Tasar, Eyal Benaroche, and Benjamin Aubin. This model is a 26.4M LoRA distilled version of SD1.5 model that is able to generate images in 2-4 steps. The main purpose of this model is to reproduce the main results of the paper. See our live demo.
How to use?
The model can be used using the StableDiffusionPipeline from diffusers library directly. It can allow reducing the number of required sampling steps to 2-4 steps.
from diffusers import StableDiffusionPipeline, LCMScheduler
adapter_id = "jasperai/flash-sd"
pipe = StableDiffusionPipeline.from_pretrained(
"runwayml/stable-diffusion-v1-5",
use_safetensors=True,
)
pipe.scheduler = LCMScheduler.from_pretrained(
"runwayml/stable-diffusion-v1-5",
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 2 H100 GPUs (representing approx. a total 26 GPU hours of training). Please refer to the paper for further parameters details.
