The story so far

Google has opened Gemini 4 Carbon to paying developers and enterprises through Google AI Studio and Gemini for business, and is rolling it out to Google AI Ultra subscribers across Antigravity, the Gemini app, and AI Mode in Search. Perplexity has also made it available in Computer to Pro and Max subscribers, and in Search to Max subscribers. Google’s introductory API price is $2 per million input tokens and $10 per million output tokens. Carbon follows Gemini 4 Argon by a few weeks. Google positions it for complex, long-horizon work such as multi-step coding, cybersecurity, and scientific research. Before this wider rollout, access began with selected cyber defenders and was set to expand through the Fairwind Program; defenders can still apply, with onboarding subject to eligibility, capacity, and selection. Google reported a score of 59 on Artificial Analysis Intelligence Index v5.0 and cybersecurity benchmark results measured without guardrails. Perplexity reported a 0.857 score on its WANDR benchmark at $5.86 per task, matching Claude Fable 5.2 at 40% of the cost.
