Google DeepMind is announcing Gemini 4 Carbon, a frontier model it says is its strongest yet for cybersecurity and long-horizon tasks, following Gemini 4 Argon two weeks earlier. Carbon ranks first on v5.0 of the Artificial Analysis Intelligence Index at 59 and leads SEC-bench Pro at 88.2% for finding vulnerabilities, ExploitGym at 54.8% for exploitation and CWE-bench at 71.0% for patching. The company says internal benchmarks show more than 2x uplift over Argon in generating secure code, and that the Chrome team reported Carbon produced high-quality patches more than 10X better than another lab's large frontier model. Rollout is deliberately staged: from this week Carbon goes to a subset of cyber defenders, with access widened gradually to trusted partners through the Fairwind Program before it reaches developers, businesses and consumers. Carbon launches at the same introductory price as Argon, $2 per million input tokens and $10 per million output tokens, with cached input tokens at 95% off the input price. Google says Carbon builds on Argon's safety stack and cut successful cheating on Terminal-Bench 4.0 to 0.0%, with high-severity misalignment alerts in internal live coding environments down almost 80%.

## Evidence

Verbatim from https://deepmind.google/blog/gemini-4-carbon-our-next-frontier-model/:

> Starting this week, we will make Carbon available to a subset of cyber defenders and will gradually phase access to additional trusted partners through our Fairwind Program . We’re continuing to gather feedback and iterate on guardrails before making Carbon available to developers, businesses, and consumers via our product surfaces as soon as possible.
