Has anyone noticed if sdxl performs poorly at resolutions as low as 256 or even smaller, leading to a higher likelihood of generating bad images? about generative-models

Yeah, it's not designed to do low resolutions – don't do that if you don't want bad images. 😁

Yes, I don't think you should go below 768 resolution with SD-XL.

Edit: Actually, the minimal value in the demo is 576.
