SDXL Turbo
SDXL Turbo, developed by Stability AI, is an open-source image generation model with 3.5 billion parameters designed for real-time image synthesis. The model generates images in a single inference step using adversarial diffusion distillation, producing results in under one second compared to the multi-step process of standard diffusion models. This speed advantage makes it suitable for interactive applications, live previews, and rapid prototyping where instant visual feedback is required. While image quality is somewhat lower than multi-step models like SDXL or Stable Diffusion 3, the speed-quality tradeoff is favorable for many practical applications. Free and fully open-source, SDXL Turbo runs on consumer GPUs and can be integrated into real-time applications. The model demonstrated that diffusion models could be distilled for near-instant generation without catastrophic quality loss.
