Google’s Carbon launch puts access rules ahead of model scores

Google announced Gemini 4 Carbon on October 28 with access initially limited to selected cyber defenders. More trusted partners are to follow through Fairwind; availability for developers, businesses and consumers remains a plan. ^[1]

Its listed introductory API rates are $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 afterward. The Carbon notice gives no introductory-period end date. ^[1]

Google says its cybersecurity benchmark scores were evaluated without guardrails. Those results describe its evaluation conditions, rather than independently established performance for a customer’s safeguarded system. ^[1]

For people choosing a service now, Google’s October 13 Argon release supplies a separate baseline. It lists paid-tier API access through AI Studio and Android Studio, and Pro or Ultra subscriber access in the Gemini app and AI Mode in Search. Argon’s own introductory-price period ends November 30. These are paid access routes, not an offer of unrestricted free use. ^[2]

The undated Fairwind reference still describes Argon, so it does not establish Carbon access for every program member. It prioritizes governments, critical infrastructure operators and core technology platforms, and vets applicants’ operating records. An application is a request for review, rather than approval or a promised start date. ^[3]

The program also requires organizations to track employee access and restrict use to internal security teams. Its governance section specifies authentication and access controls, and prohibits sharing or reselling model access. For an organization evaluating the new release, eligibility and operating responsibilities therefore matter alongside model scores. ^[3]
