Google makes Gemini 4 Carbon available to developers, businesses and consumers

What's new

Google announced on Nov 10, 2026 that Gemini 4 Carbon is available to developers, enterprises, scientists and consumers. The company describes Carbon as its strongest model, with frontier performance in cybersecurity and long-horizon agentic work such as software engineering and scientific reasoning. Google says Carbon uses more tokens than Gemini 4 Argon to reason deeply and run extended verification loops, while Argon remains its choice for most software engineering and knowledge work. Google is also previewing a /swarm feature in Google Antigravity that turns one prompt into a coordinated team of agents.

Why it matters

Paying developers and enterprises can use Carbon through Google AI Studio and Gemini for business, and Google AI Ultra subscribers get it in several products. Google says Carbon ranks #1 on CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench at more than 2X lower cost per task than the next best external model, and #2 on a new Multimodal Knowledge Agent benchmark made with Artificial Analysis. These are the company's claims. Google also says cybersecurity capabilities are offered through its Fairwind Program, which gave early access to defenders two weeks earlier.

Details

Carbon is available via the API in Google AI Studio and Gemini for business for all paying developers and enterprises. Google lists the introductory price, the same as Argon, as $2 per million input tokens and $10 per million output tokens. It is rolling out to all Google AI Ultra subscribers in Google Antigravity, the Gemini app and AI Mode in Search. Google says it is expanding Carbon access for scientists in its program offering free Antigravity access for six months to 10,000 scientists, with applications open and onboarding weekly, subject to eligibility, capacity and selection. The /swarm feature is a preview.
