Gemini 4 Carbon expands access, with Ultra rollout and introductory API rates through November
Google’s new November 10 announcement expands October’s restricted access to paid API, enterprise and Ultra users.
Google announced broader Carbon access on November 10: the paid Gemini API in AI Studio and enterprise access, plus a rollout to Ultra subscribers in Antigravity, Gemini and Search AI Mode. This advances October 28’s restricted release; Free or Pro entitlement is not established.
Public-model API rates are US$2/10 per million input/output tokens. After the introductory period expires November 30, 2026, rates become US$4/20; the transition timezone is unstated. These are not local subscription quotes. Additional charges and exact quotas remain unverified.
Ultra and Gemini web support lists include Hong Kong, Macau and Taiwan. Ultra requires a personal Google Account; AI Studio/Antigravity require age 18 or older. Gemini web lists Simplified, Traditional and Hong Kong Chinese. These general permissions do not establish Carbon access everywhere. Carbon-specific language restrictions, mobile OS/version requirements and local activation remain unconfirmed. The API regional-document URL redirected to an official 404 during this check; no old list was substituted. No login or testing was performed.
