Google makes Gemini 4 Carbon available to paying developers and enterprises
Google's post dated 10 November 2026 says Gemini 4 Carbon is now available to developers, enterprises, scientists and consumers. It says Carbon is available via the API in Google AI Studio and Gemini for business for all paying developers and enterprises, at the same introductory price as Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens. A footnote says that after the introductory period expires on 30 November 2026, the price of $4 per 1M input tokens and $20 per 1M output tokens will apply, and that this applies to the Carbon model intended for public access only. The post does not state a context window. It does not restate a cached-input price.

Google's post dated 10 November 2026 says Gemini 4 Carbon is now available to developers, enterprises, scientists and consumers. It says Carbon is available via the API in Google AI Studio and Gemini for business for all paying developers and enterprises, at the same introductory price as Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens. A footnote says that after the introductory period expires on 30 November 2026, the price of $4 per 1M input tokens and $20 per 1M output tokens will apply, and that this applies to the Carbon model intended for public access only. The post does not state a context window. It does not restate a cached-input price.
The post says Carbon is also rolling out to all Google AI Ultra subscribers in Google Antigravity, the Gemini app and AI Mode in Search. For everyday users, the getting-started section says to try Carbon in the Gemini app and AI Mode in Search if they are a Google AI Ultra subscriber. It says that two weeks ago Carbon was released to a set of cybersecurity defenders through the Fairwind Program, and that cybersecurity teams apply to that program for Carbon for cyber. It says access to Carbon is being expanded for current and future participants in a program that offers scientists access in Google Antigravity, with onboarding still subject to eligibility, capacity and selection.
On its own tests, the post says Carbon's safeguards lowered the per-attempt breach rate to 0.8%, down from 3.1% on Argon, and lowered the automated cyberattack query success rate to 2.17% in Gray Swan's testing, compared with 9.86% on Argon. Those figures are Google's.
What it means for business: paying developers and enterprises can call Carbon in the API at the introductory prices above, and the footnote dates the change to $4 and $20 per 1M tokens on 30 November 2026 for the public-access model. Use in the Gemini app is described for Google AI Ultra subscribers. Cybersecurity access is still through the Fairwind Program. This describes the post. It is not advice on connecting the model to a system.
