Google announces Gemini 4 Carbon as its next frontier model, ranking #1 on the v5.0 Artificial Analysis Intelligence Index with a score of 59. Carbon delivers state-of-the-art cybersecurity capabilities, achieving 88.2% on SEC-bench Pro for vulnerability detection and leading in Exploit Gym and CWE-bench benchmarks. The model shows significant gains in coding, agentic tasks, and long-horizon engineering problems, jumping +89 elo points to #4 (1768) on Web Dev Arena.
Building on Gemini 4 Argon, Carbon enables sustained agentic workflows for complex multi-step tasks like root-cause analysis and patching subtle bugs across large codebases. Google is rolling out Carbon to a subset of cyber defenders via the Fairwind Program, with plans to expand access gradually. Pricing matches Argon at $2 per million input tokens and $10 per million output tokens, with cached inputs at 95% off.
