Supposedly Stable Diffusion was trained on 512 x 512 images, so it's not clear that it will work well for larger images even if you had the RAM.

To generate larger images, it is standard practice to generate 512 x 512 and then use a separate tool to upscale, and maybe a second separate tool to improve the face. The Windows versions of SD environments are starting to incorporate these additional tools, but the Apple Silicon versions of SD environments are lagging behind due to Pytorch metal limitations.... It'll hopefully sort itself out in the next few months.
