The speaker expects a diffusion model forced to produce small details before large-scale structure to perform poorly as a model.

“Uh I would imagine that most that they say in models would structure it like this. This doesn't mean that you couldn't build a diffusion model which doesn't do that. I could imagine going and kind of enforcing effectively a constraint that says well you have to do the the small things first. I don't think it would be a good model. Uh you might need like let's say thousands of times more parameters to actually uh fit this. You you still would be uh you still would be able to”
