Google DeepMind Introduces Gemini 4 Carbon, Its Top Model for Cyber Defense and Coding

Google DeepMind introduced Gemini 4 Carbon, a frontier model built for long-horizon agentic coding and cybersecurity defense, which ranks #1 on the v5.0 Artificial Analysis Intelligence Index with a score of 59. It leads 15 of 17 published benchmarks versus Gemini 4 Argon, GPT-6 Astra, Claude Opus 5.5 and Claude Fable 5.1, including SEC-bench Pro (88.2%), ExploitGym (54.8%) and GraphWalks (96.2%), though it trails Claude Opus 5.5 on OSWorld-2.1 (81.5% vs 87.2%) and GPT-6 Astra on FrontierSWE (61.2% vs 65.5%). Access begins with a vetted group of cyber defenders and the Fairwind Program rather than the public API, at an introductory price of $2 per million input tokens and $10 per million output tokens.
