I'd suggest using a cloud VM with a GPU attached. For normal stuff like LLM inference, I just rent an instance with a small (cheap) GPU. But when I need to do something more exotic like train an image model from scratch, I can temporarily spin up a cluster that has high-end expensive A100s. This way I don't have to invest in expensive hardware like an M3 that can still only do a small part of the full range.
