8GB is enough to do 1080p resolution. the UI i use for SD maxes out at 2048x2048. however, it takes a lot longer than 512x512 to generate: 1m40s versus 1.97s.
I'm guessing if one had access to one of those nvidia backplane rackmount devices one could generate 8k or larger resolution images.
SD can’t generate coherent images if you increase the output size. They’re basically always unusable unless you don’t need any global architecture to them.
I'm not sure what you mean. with the 1.4 checkpoint i can make a scene "a sky full of blimps" and then img2img that into a space battle where all the blimps in the sky are either fires or spacecraft afterburners. at 2k pixels, and then use the built in "GAN" stuff to bring it to 4k, 5k, or 8k.
It isn't perfect and it takes a lot of fiddling and sysadmin stuff, but it is way better than nextchar = CHR$(RAND64); color = (rand65535); of yore.
