InstaFlow: One Step is Enough for High-Quality Diffusion-Based Text-to-Image Generation 

Introducing InstaFlow: A game-changer in text-to-image generation! This one-step diffusion model, leveraging Rectified Flow's 'reflow' technique, achieves SD-level image quality in milliseconds. With an FID of 23.3 on MS COCO 2017-5k and training taking just 199 GPU days, InstaFlow sets new standards in speed and quality.
