Stable Diffusion XL Turbo can generate AI images as fast as you can type

Nov 30, 2023 - arstechnica.com
Stability AI has launched Stable Diffusion XL Turbo, an AI image-synthesis model that can rapidly generate images based on a written prompt. The model's primary innovation is its ability to produce image outputs in a single step, a significant reduction from the 20–50 steps required by its predecessor. This leap in efficiency is attributed to a technique called Adversarial Diffusion Distillation (ADD), which uses score distillation and adversarial loss to improve the realism of the output.

Currently, SDXL Turbo is available under a non-commercial research license, limiting its use to personal, non-commercial purposes. Despite facing internal management issues, Stability AI continues to release new products, including Stable Video Diffusion, which can turn still images into short video clips. The company offers a beta demonstration of SDXL Turbo's capabilities on its image-editing platform, Clipdrop, and an unofficial live demo on Hugging Face.
