You may mean Gemini 1.0 Pro, which is the paid version of what used to be bard. Unfortunately Gemini Ultra is not available right now, and it seems Gemini 1.5 Pro (potentially similar to Ultra 1.0) may be available by waitlist.
The free tier of Gemini (formerly Bard) has been on Gemini Pro 1.0 for a bit now.
This has some serious implications for OpenAI as Gemini Pro 1.5 that is tested here indeed seems to beat their premium tier, assuming Google will keep using these tiers for what's paid and not.
