I was drawn to Gemini Pro because it had function/tool calling... but it works terribly. (I haven't tried Gemini Ultra yet; unclear if it's available by API?)
Anyway, probably best that they didn't release support that doesn't work.
Gemini Ultra is not available via API yet, at least according to the Google reps we talked with today. There's a waiting list. I suspect they are figuring out how to charge for API access, among other things. The announcement today only seemed to have pricing for the "$20/month" thing.
