Why the fuck wasn't this posted here, you fucking redditor weebs?

It's a magical 2D art scaler/denoiser. Someone should give it one of those 320x420 dakimakura samples and post the results.

I want to see how it does with photos after it's been trained with photos instead of anime girls.

I but I definitely don't want to spend time trying to grok all this CUDA nonsense. Can I run it (even slowly) on a $100 graphics card or not?

Don't get me wrong, GPU stuff is neat and all that and I'm sure it lends to this process in some way but hardware companies are awful and all these proprietary APIs are cancer.
