Gemini 4 expands its frontier benchmark and tooling push

Gemini 4 Carbon reportedly scores 59 on Artificial Analysis v5, 88.2% on SEC-bench Pro, 54.8% on ExploitGym, and 71.0% on CWE-bench, but trails Claude Opus 5.5 on the Coding Agent Index and has limited independent access. New coverage reports introductory API pricing of $2/$10 per million input/output tokens, rising to $4/$20 after Nov. 30; task costs can differ substantially from token rates. Individual tester claims about cheating and prompt-injection resistance lack methodology and independent validation.
