I haven’t tried it, and not the norm, but I agree it should be more common. We have a global supercomputer with higher latency, but still a supercomputer.
I might just still be too tired from just waking up, but I can’t for the life of me find any details on that site about what models are actually being served by the horde?
Go to https://aihorde.net/api/, scroll down to /v2/status/models, and click Try it out and then Execute. It's an enormous list and I think it can be dynamically updated, so that's probably why it isn't listed on the website.
