Google DeepMind announces Gemini 4 Carbon, its strongest AI model with state-of-the-art cybersecurity and long-horizon capabilities

Google DeepMind has unveiled Gemini 4 Carbon, its most powerful AI model to date, ranking #1 on the Artificial Analysis Intelligence Index v5.0 with a score of 59. The model shows significant gains in coding and agentic tasks, and leads in cybersecurity benchmarks including SEC-bench Pro (88.2%), ExploitGym (54.8%), and CWE-bench (71.0). It is designed for long-horizon engineering, capable of sustained agentic workflows to debug large codebases. Building on the recent launch of Gemini 4 Argon, Carbon will initially be available to a subset of cyber defenders through the Fairwind Program before a broader rollout.
