Funny that of all the "This X does not exist" sites, this one only gives relatively small, low-res pictures. Because I'd totally print out some of that stuff and hang it up!

This generator of all of them seems to raise the more existential questions. What does it mean to exist? Surely art is art regardless of whether it's on a physical canvas. Just the act of generating it and serving pixels changes the state from "doesn't exist" to "does exist"...
The problem is more that you hit diminishing returns fast from training at higher resolutions. There's not too much difference between training at 1024px or training at 512px and using an off-the-shelf superresolution NN upscaler, but the latter is like 4x faster. So why bother? You don't always even have input data which is 1024px+.
