There is something similar to what you described operating right now: Stable Horde: <a href="https://stablehorde.net/" rel="nofollow">https://stablehorde.net/</a><p>I'm not sure if it has the priority queueing system you mentioned, or how much it has generalized to non-SD loads, but it is functional.<p>Also, you should consider using a Huggingface diffusers UI/backend instead of the automatic1111 UI, which is based on (and now inextricably linked to) the old Stability AI implementation. Maybe thats fine now, but its already a problem for optimizations people are cooking up (like Facebook's AITemplate, torch.compile, SHARK/MLIR for AMD GPUs, Intel OpenVINO...) which work with diffusers already.<p>I am bouncing between InvokeAI and VoltaML at the moment (as I cant get any of the optimizations to work in the auto1111 implementation anymore), but I can hardly keep up with everything on Github.
