What is SDXL Lightning?
SDXL-Lightning is a quick text-to-image model that can generate high-quality 1024px images in a matter of seconds. It is derived from the stability AI/stable-diffusion-xl-base-1.0 model and includes checkpoints for one-, two-, four-, and eight-step distillation models. The repository includes both full UNet and LoRA checkpoints, with full UNet models providing the highest quality and LoRA models applicable to other base models. SDXL-Lightning can be used with either the Diffusers library or ComfyUI, and the authors provide detailed instructions for each scenario.
