Stanford U & Google Brain’s Classifier-Free Guidance Model Diffusion Technique Reduces Sampling Steps by 256x

In the new paper On Distillation of Guided Diffusion Models, researchers from Google Brain and Stanford University propose a novel approach for distilling classifier-free guided diffusion models with high sampling efficiency. The resulting models achieve performance comparable to the original model but with sampling steps reduced by up to 256 times.

OpenAI’s unCLIP Text-to-Image System Leverages Contrastive and Diffusion Models to Achieve SOTA Performance

In the new paper Hierarchical Text-Conditional Image Generation with CLIP Latents, an OpenAI research team combines the advantages of contrastive and diffusion models for text-conditional image generation tasks. Their proposed unCLIP model improves image diversity with minimal loss in photorealism and caption similarity, and produces image quality comparable to the state-of-the-art text-to-image system GLIDE.
