Paying users can access Gemini 4 Carbon now; launch token rates are set to double, though outlets differ on the date.

Google made Gemini 4 Carbon available on November 10 to paying developers, enterprises, and Google AI Ultra subscribers through the Gemini API, AI Studio, Gemini for business, Antigravity, the Gemini app, and Search AI Mode. The Decoder also lists Android Studio. Introductory pricing matches Gemini 4 Argon at $2 per million input tokens and $10 per million output tokens, later rising to $4 and $20. Google says Carbon targets long-horizon coding, research, and cybersecurity and leads CursorBench 4.0, WANDR, and AutomationBench, while The Verge reports Google’s cited benchmarks place it behind Fable 5.2. SecurityWeek says cybersecurity use remains in Fairwind, which began about two weeks earlier. Some vulnerability details remain under disclosure.
