This task requires a bit more work than I'd want, but I'd also point out $100k can buy ~9 A100's which are good for ~7k hours of work a month (through not entirely reputable channels, so there's a chance some might die earlier or might have to be returned). That might not train Stable Diffusion in a fast enough time for you (~50k hours estimated training time), but it's still damned impressive. And you can keep the hardware.

I wonder if AMD is as over-the-top brutal with legal control over where their GPUs can be used as Nvidia is. Maybe with energy cost you might possibly still want to stick with the A100's anyways, but you can afford quite a lot of RX 7900's with $100k (if you can find em).
