Github's profile pictures are 40x40px in issues/pr's/commits/etc, they're very rarely seen above that, and I think sdxl lightning creates acceptable 1024x1024 images in many cases - downscaling to 512x512 hides a lot of the "ai artifacts"

Places like steam, discord, etc you very rarely see profile pictures above that size.

The use case is you can print out the great images and put them on your wall for decoration.

It is just art. I think AI art shows what obsessed gadget makers for profit we have become culturally. We can't even figure out that the use case for art is hanging on the wall for decoration. For a conversation piece. A few will have their name become known and make it into galleries.

Infinite supply means the value tends towards zero.Good luck monetizing anything with those economic characteristics.
