# SDXL-Lightning

**SDXL-Lightning** is a state-of-the-art text-to-image generation model designed for both **speed** and **quality**, capable of producing **high-resolution 1024px images** in remarkably few steps.

Built upon the foundation of [`stabilityai/stable-diffusion-xl-base-1.0`](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0), it leverages *Progressive Adversarial Diffusion Distillation* to achieve rapid yet powerful image synthesis.

## Features - 🚀 **Lightning-fast inference** with 1-step, 2-step, 4-step, and 8-step distilled models. - **2-step, 4-step, and 8-step** models deliver outstanding image quality. - **1-step** model is experimental, exploring the limits of extreme efficiency.

- 🧩 **Model formats**: - **Full UNet checkpoints** – deliver the best image quality. - **LoRA checkpoints** – lightweight and easily applied to other base models.

## Open Source We release SDXL-Lightning fully open-sourced as part of our research to empower the community with cutting-edge fast diffusion technology. For more details, please see our paper: **SDXL-Lightning: Progressive Adversarial Diffusion Distillation**.
