Gemini 4 Carbon is announced, with access limited to select cyber defenders

Google's own announcement, dated 28 October 2026, says it will make Carbon available to a subset of cyber defenders and phase access to additional trusted partners. That is a restricted rollout, not general availability. Reporting on 29 October likewise said the model is not broadly available yet and is being opened in stages through the Fairwind Program. The forecast leans against a public release on Wednesday 11 November because the only date-specific evidence is an estimate, not a Google commitment. Ars Technica reported that Google makes no promises about a wide-release timeline, adding that if it resembles Argon, the model could be available in a couple of weeks. That is a comparison, and the window it points to is loose. There are signs of launch preparation. Google published introductory pricing of $2 per million input tokens and $10 per million output tokens, matching Argon. Its blog also said it is gathering feedback and iterating on guardrails before offering Carbon to developers, businesses and consumers "as soon as possible", and that it is engaged in the U.S. government's voluntary pre-release testing process. Neither point gives a date. A single named day is a narrow target. A public launch could come before or after it, and either would leave this question unmet. The supplied reporting does not say which is more likely. The thing to watch is whether Google announces Carbon for developers or consumers on its product surfaces, and on what date.
