Google said on November 10 that Gemini 4 Carbon, which it calls its strongest model, is rolling out to Google AI Ultra subscribers in AI Mode in Search, the Gemini app and Google Antigravity. Carbon went to a group of cybersecurity defenders two weeks earlier. Developers and enterprises get it through the API at the same introductory price as Gemini 4 Argon. Google's post names only Ultra for the consumer rollout; Argon reached AI Mode for Pro and Ultra subscribers on October 13. The post does not say whether Carbon appears in AI Mode's model menu or what it changes for Search answers.

Why it matters: Google is putting its top model in AI Mode behind its highest-priced subscription tier, so the strongest answers in AI Mode now reach only a small paying slice of its users.
