Google has expanded access to Gemini 4 Carbon, bringing the model to paying API customers and Google AI Ultra subscribers after an earlier release to selected cybersecurity defenders.
In its November 10 announcement, Google says developers and enterprises can use Carbon through AI Studio and Gemini for business. Ultra access is rolling out across Antigravity, the Gemini app and AI Mode in Search.
The introductory API rate is $2 per million input tokens and $10 per million output tokens.
Antigravity’s /swarm feature for coordinating multiple agents remains in preview. Teams considering production use should account for that status.
Google reports stronger cybersecurity and coding performance and improved safety evaluations. These are company-reported results, independently unverified by DaySec. Access to Carbon for cyber remains application-based through Google’s Fairwind Program, separate from the broader rollout.
