SDXL Flash in collaboration with Project Fluently

Introducing the new fast model SDXL Flash, we learned that all fast XL models work fast, but the quality decreases, and we also made a fast model, but it is not as fast as LCM, Turbo, Lightning and Hyper, but the quality is higher. Below you will see the study with steps and cfg.

Steps and CFG (Guidance)

Optimal settings

Steps: 6-9
CFG Scale: 2.5-3.5
Sampler: DPM++ 2S

Diffusers usage

pip install torch diffusers

import torch
from diffusers import StableDiffusionXLPipeline, DPMSolverSinglestepScheduler

# Load model.
pipe = StableDiffusionXLPipeline.from_pretrained("sd-community/sdxl-flash", torch_dtype=torch.float16, variant="fp16").to("cuda")

# Ensure sampler uses "trailing" timesteps.
pipe.scheduler = DPMSolverSinglestepScheduler.from_config(pipe.scheduler.config, timestep_spacing="trailing")

# Image generation.
pipe("a happy dog, sunny day, realism", num_inference_steps=7, guidance_scale=3).images[0].save("output.png")
