It doesn't. MPS largely is on GPU. PyTorch's MPS implementation is incomplete a few weeks ago as well. This is about 3x faster.



Is it? I just ran it on my M1 MacBook Air and am getting 3 it/sec, same as I was using Stable Diffusion for M1. Maybe I'm doing something wrong?


That's surprising to me, although I did the look about 3 weeks ago, and MPS support is a moving target. It is just M1 without Pro or Ultra right? Also, diffusers does support different backends other than PyTorch.
