Wait for ASICs. When I started mining bitcoin on dual core cpus I would have never believed a little USB stick would be doing 100x what 30 of those full sized pcs could. The software behind generative models still needs to be fleshed out for hardware to know what direction to go. But a little AI machine that only draws like 50w max but has 256gb of high speed RAM for model storage is not far away. Anyone with $500(or whatever idk) will be able to order a machine off ebay, load it up with whatever models they want, and start generating whatever they want locally.
