DeepMind announces Gemini 4 Carbon with limited access

Google said on Oct. 28, 2026 that Gemini 4 Carbon is its next frontier model, at introductory prices of $2 per million input tokens and $10 per million output tokens, the same introductory rates as Gemini 4 Argon. Access this week is limited to a subset of cyber defenders in the Fairwind Program while a U.S. government voluntary pre-release review continues, and the later price of $4 and $20 per million tokens has no published end date for the introductory period. Google reports a score of 59 and first place on Artificial Analysis Intelligence Index v5.0, plus 88.2% on SEC-bench Pro, 54.8% on ExploitGym, and 71.0% on CWE-bench.
