I don't know either tbh. I wouldn't be surprised it the answer is no (and it will come later or something like that)
I also tried to use Gemini 3 in my Gemini CLI and it's not available yet (it's available to all Ultra, but not all Pro subscribers), I needed to sign up to a waitlist
All in all, Google is terrible at launching things like that in a concise and understandable way
Back in the early 00s having a 'waitlist' for gmail with invites was an exciting buzz-making marketing technique and justifiable technically.
This is just irritating. I am not going to give them money until I know I can try their latest thing and they've made it hard for me to even know how I can do that.
I poked around and couldn't figure this out.
