What changed

Google DeepMind says Gemini 4 Carbon scored 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation, and 71.0% on CWE-bench for patching.

Access begins this week for a subset of cyber defenders, with Google DeepMind planning to expand gradually to additional trusted partners through its Fairwind Program. Developers, businesses and consumers are expected to get access later, after the company gathers feedback and iterates on guardrails.

Google DeepMind says Carbon will launch at the same introductory API prices as Argon: $2 per million input tokens and $10 per million output tokens.

The company also says Carbon achieved a 0.0% attack success rate across evaluated attempts on Gray Swan’s Indirect Prompt Injection benchmark, and that high-severity misalignment alerts in its internal live-coding tests fell by almost 80%.
