Is there a lower resolution model for running this project on lower-end GPUs?

[illtellyoulater]

Hello! I know this request may seem strange but is there any lower resolution model for those of us running on very modest GPUs who still would like to try to run this project?
I already tried lowering the batch size down to 1 and the image size too but it didn't help...
Also I know I can run this on CPU, but that way it seems to be taking ages to complete 1 single step :)
And I also know that there could be colabs for running it, but I want to run it on my own metal ;)
So yeah I really hope there's something like a smaller model we could use? (It doesn't matter it will look crap, I will be content with that! :) )
Thanks a lot in advance!
