I just want to point out that I’ve noticed sdxl isn’t good at producing images that are 512x512 for some reason. It works much better with at least 768x768 resolution.
Fair point, although in my experience SDXL still isn't great at non-square ratios. I end up just cropping them to the ratio I want.
What have you seen to be the issue? Composition? Realism? Prompt adherence? I’m just finishing a project having generated tons of images at a mix of ~6 aspect ratios and I haven’t noticed any difference.
Indeed, however one of the listed limitations is:
The generated images are of a fixed resolution (512x512 pix), and the model does not achieve perfect photorealism.
