Würstchen is a diffusion model, whose textconditional model works in a highly compressed latent space of images. Why is this important? Compressing data can reduce computational costs for both training and inference by magnitudes. Training on 1024x1024 images is way more expensive than training on 32x32. Usually, other works make use of a relatively small compression, in the range of 4x 8x spatial compression. Würstchen takes this to an extreme. Through its novel design, we achieve a 42x spatial compression.
