If you are a programmer at heart, ComfyUI will feel very comfortable (pun intended). It's basically a visual programming environment optimized for the type of compositional programming that machine learning models desire. The next thing this space needs is someone to build an API hosting every imaginable model on a vast farm of GPUs in the cloud. Use ComfyUI and other apps to orchestrate the models locally, but send data to the cloud and benefit from sharing GPU resources far more efficiently.

If anyone has a spare thousand hours to kill, I would build that and connect it up with the various front-ends including ComfyUI, A111, etc.. not a small amount of effort, but it will be rewarding.
