Google Releases Gemini 4 Carbon, a Frontier Model Focused on Cybersecurity

Key Info

Google introduced Gemini 4 Carbon, its next frontier model, just two weeks after Gemini 4 Argon. It ranks #1 on the updated v5.0 Artificial Analysis Intelligence Index with a score of 59 and sets state-of-the-art results in cybersecurity and long-horizon capabilities.

Highlights

• Carbon scores 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation, and 71.0% on CWE-bench for patching.
• It shows significant improvements in long-horizon tasks compared with Argon, including autonomous coding and the cybersecurity defense lifecycle (detection, validation, remediation).
• Google says frontier safeguards have been strengthened.
• Rollout starts this week to a subset of trusted cyber defenders through the Fairwind Program, with expanded access planned soon.
