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.

Is this not simply some sort of watermark instead of an artifact?
No, it's probably their rope implementation. They had a similar problem with the old qwen image but to be sure it needs some digging.

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.
