The main limitation for running these AIs is that you need tons of VRAM available for your GPU to get any good performance out of them. I don't have a video card with 12GiB of VRAM and I don't know anyone who does.

If you're willing to wait more (30 seconds per image, assuming limited image sizes) there are repositories that will run the model on the CPU instead, leveraging your much cheaper RAM.

In theory you could swap VRAM in and out in the middle of the rendering process, but this would make the entire process incredibly slow. I think you'll have more success just running the CPU version if you're willing to accept slowdowns.
