Google releases Gemini 4 Carbon first to cyber defenders
The benchmark results and safety figures are Google's own; no independent rerun was found. Google gives no date for access by developers, businesses or consumers, and no length for the introductory pricing period. Benchmark scores do not show how the model performs in a defender's own environment.
What was claimed?
Google announced Gemini 4 Carbon on October 28, 2026, two weeks after Gemini 4 Argon, describing it as its strongest model for cybersecurity and long-running engineering work. Google says it will make Carbon available this week to a subset of cyber defenders and then phase in trusted partners through its Fairwind Program. Google reports 88.2% on SEC-bench Pro, 54.8% on ExploitGym and 71.0% on CWE-bench, evaluated without guardrails, and a score of 59 on version 5.0 of the Artificial Analysis Intelligence Index. Google says Carbon will launch at Argon's introductory price of $2 input and $10 output per million tokens, rising to $4 and $20 after the introductory period.
What does the evidence support?
Company claim, independent confirmation unresolved
This is another frontier model released first to vetted security users rather than the public, because the provider judges its ability to find and exploit software flaws to be high. Google says it is taking part in the U.S. government's voluntary pre-release testing process.
What are the limits?
The benchmark results and safety figures are Google's own; no independent rerun was found. Google gives no date for access by developers, businesses or consumers, and no length for the introductory pricing period. Benchmark scores do not show how the model performs in a defender's own environment.
