>>26488For one, I believe you can run it on CPU/RAM only if you have enough, it will just generally be much slower.
I don't have a 4GB VRAM device and I'm running it. But newer higher-res models trained on larger pics (e.g. 1024x1024 pics instead of 512x512 pics) or any upscaling to a larger output requires using tiling (generating e.g. 4 smaller images to make one big image) or just using CPU mode. So 4GB would be the
recommended, at least for whenever model they were talking about.
