Important note on Infomaniak's offering - when they first launched it, I gave it a try but despite claims that it's OpenAI API compatible, even basic things like sending a base64 encoded image were broken. I reached out to their support, who replied with (verbatim): "Unfortunately, we do not provide support for our AI Service, as the solution is highly unmanaged and uses our API."

"highly unmanaged" didn't fill me with confidence, and "uses our API" is a very weird reason to give for not offering support. I wrote off ever using them for anything beyond email after that reply.
