Looking at the output image examples, very nice, although they seem a little blurry. But I guess that's a dataset issue? Have you tried training anything above 1024x1024? Hope someone releases a model based on this since open source pixel space models are a rarity afaik

the FFHQ-1024 examples shouldn't be blurry. you can download the originals from the project page[0] — click any image in the teaser, or download our 50k samples.

the ImageNet-256 examples also aren't typically blurry (but they are 256x256 so your viewer may be bicubic scaling them or something). the ImageNet dataset _can_ have blurry, compressed or low resolution training samples, which can afflict some classes more than others, and we learn to produce samples like the training set.
