I don't have an M1 Mac, I have an Intel one with an AMD GPU, not sure if i can run it? don't mind if it's a bit slow, or what is the best way of running it in the cloud? Anything that can product high res for free?
And this should work on an AMD GPU (I haven't tried it, I only have NVIDIA): https://github.com/AshleyYakeley/stable-diffusion-rocm
There are also many ways to run it in the cloud (and even more coming every hour!) I think this one is the most popular: https://colab.research.google.com/github/altryne/sd-webui-co...
It's not free but I've played with it a lot over the last two days for around $10, generating the most complex photos I can (1024x1024, 150 steps, 9 images, etc)
i am runnig it on my 2019 intel macbook pro. 10 minutes per picture

it's for, but it could be adapted to Linux as.lomg as you install the right drivers and such.
Looks like it's going to be a lot of fun though.
