Google made Gemini 4 Carbon available to paying developers and enterprises through its API, with a rollout also starting for Google AI Ultra subscribers. Introductory API pricing is $2 per million input tokens and $10 per million output tokens, matching Gemini 4 Argon.

Google says Carbon targets complex coding, scientific reasoning and extended workflows, using more tokens than Argon for exploration and verification. It is also previewing a tool in Google Antigravity that coordinates multiple agents across separate workspaces.

The company is expanding its scientist access program to include Carbon. Access for researchers remains subject to eligibility, capacity and selection; specialized cybersecurity access runs through the Fairwind Program.
