Google launches Gemini 4 Carbon with a ‘significant leap’ in cybersecurity

Google released Gemini 4 Carbon, a frontier model it says offers significant gains in coding, agentic tasks, and cybersecurity, and which tops the Artificial Analysis Intelligence Index (v5.0) benchmark ahead of Claude Opus 5.5 and GPT-6 Astra. It is currently available only to a select group of cybersecurity defense companies, with plans to expand to other partners in its Fairwind Program, and Google says it leads SEC-bench Pro and ExploitGym while running longer multi-step tasks and cutting unsupported claims by two times versus Argon. It launches at the same introductory price as Argon, $2 per million input tokens and $10 per million output tokens.
