Google releases Gemini 4 Carbon to cyber defenders only

Verdict: Vendor-reported · Model releases · AI security

The release is real and its #1 index rank is independently confirmed, but access is gated and the cyber scores are self-reported.

Google released Gemini 4 Carbon on 28 October, but only to a subset of cyber defenders.

  • Claim: State-of-the-art cyber scores (SEC-bench Pro 88.2%, ExploitGym 54.8%, CWE-bench 71.0%) and #1 on the Artificial Analysis Intelligence Index with 59. Google
  • Evidence: Artificial Analysis confirms the index score and rank. On its Coding Agent Index, Carbon with Antigravity CLI scores 59, behind Claude Code with Claude Opus 5.5 (max) at 62. Artificial Analysis
  • Caveats: The cyber scores are self-reported and the post does not say who ran them. The Chrome patch and secure-code comparisons are internal. Google, The Batch
  • Why it matters: There is no public API and no date, so nobody outside the Fairwind Program can test it. Price is $2/$10 per million tokens, rising to $4/$20. Google
