    They finally fixed their VAE. It really held back their models over the last 2 years.

    EDIT: It still produces artifacts it's better but unusable for production work. In midvalues you will see a slight dot pattern.

      Can you share the sources?

        It's right there in the hugging face link?

        latents go from 16ch @ 8x compression to 64ch @ 16x, so roughly the same total latent budget but much more channel heavy. It’s also deeper/wider, and the old 2x2 transformer patching is gone.

        On some images it still produces artifacts but can't say if it's the transformer or the VAE yet.
