Summary

Google announced Gemini 4 Carbon, a new frontier AI model that ranks #1 on the AI Index v5.0 and excels in cybersecurity tasks including vulnerability detection, exploitation validation, and patch generation. The model demonstrates improved alignment, collaboration, follow-through on multi-step tasks, and resistance to prompt injection attacks, with a 2x performance uplift in secure code generation compared to previous versions.

    Introducing Gemini 4 Carbon, our latest frontier model. Carbon delivers improved performance across domains — ranking #1 on v5.0 of the @ArtificialAnlys Intelligence Index and sets a new state-of-the-art in cybersecurity and long-horizon capabilities. It’s rolling out starting this week to cyber defenders through our Fairwind Program, with expanded access coming soon 🧵

    We built Carbon to handle high-pressure tasks with stronger alignment, transparency, and follow-through. In testing, we saw improvements across: 🔵 Cyber defense: It achieves state-of-the-art cybersecurity performance across vulnerability detection, validation, and remediation — so defenders can stay ahead of threats. 🔵 Improved collaboration when things are unclear: Instead of guessing or cutting corners around missing info, Carbon flags discrepancies up front and asks before acting. 🔵 Following through without overstepping: Carries out multi-step plans from start to finish while staying in scope and respecting project boundaries. 🔵 Resisting prompt injection: Achieves achieves 0.0% on Gray Swan’s Indirect Prompt Injection Benchmark — resisting every evaluated attack attempt.

  3. #3

    Carbon delivers state-of-the-art performance across the cybersecurity defense lifecycle: 🔵 Finding real vulnerabilities: 88.2% on SEC-bench Pro 🔵 Validating risk through exploitation: 54.8% on ExploitGym 🔵 Patching at the root cause: 71.0% on Collinear’s CWE-bench On internal benchmarks, Carbon drives a more than 2x uplift in success rate for generating secure code over Gemini 4 Argon.

    With Carbon, our goal is to deliver frontier performance without compromising on safety. We’re rolling it out starting this week to cyber defenders through our Fairwind Program, with expanded access coming soon for developers, businesses, and consumers. Learn more ↓ goo.gle/3Wgbi9a
