Gemini 4 Carbon FAQ
What is Gemini 4 Carbon?
Gemini 4 Carbon is Google's October 28, 2026 frontier model for cybersecurity and long-horizon work. Google says it will launch at the same introductory price as Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens, with cached input at 95% off the input price. After the introductory period the price is $4 input and $20 output per million tokens. Google does not name the end of the introductory period. Access starts with a subset of cyber defenders, then additional trusted partners through the Fairwind program. It is not yet on developer, business, or consumer surfaces, and the public Gemini API model list checked October 30, 2026 still lists Gemini 4 Argon as the only Gemini 4 model.
