And if so, what interfaces can connect to them, and how do they do that?
I want to analyze with Lc0, but I don't have a computer with a GPU; I could rent one for a short time period at various cloud providers, but then I don't know what GUI I could use to talk to an engine running somewhere on the Internet.
Do e.g. Chessbase, Scid, Aquarium etc have a feature to work with engines running in the cloud?
