Frontier flagship models
Gemini 4 Carbon
Made by Google
Google's October 28, 2026 frontier model for cybersecurity and long-horizon agentic work, in limited early access.
What it is
Google announced Gemini 4 Carbon on October 28, 2026 as its strongest model, with a focus on cybersecurity and long-horizon agentic work. It is rolling out first to a limited group of cyber defenders through Google's Fairwind Program; Google says wider developer, business and consumer access will follow.
Google lists introductory API pricing of $2 per million input tokens and $10 per million output tokens, matching Gemini 4 Argon, rising to $4 and $20 after the introductory period.
Google reports SEC-bench Pro 88.2%, ExploitGym 54.8% and CWE-bench 71.0%, and first place on the Artificial Analysis Intelligence Index v5 at 59. The security scores are the maker's own figures, not independent verification.
