That doesn't sound like compression, that sounds like a way to look up a stored picture from a massive dataset that's been turned into neural net goo. I'm guessing the neural nets that can do that are WAY bigger than a 512px wide jpeg and a jpeg renderer. It's still cool, but calling that compression is like calling a link to a website compression.
