Google is expanding its AI cybersecurity work with Gemini 3.5 Flash Cyber, a new model built to help identify and fix software vulnerabilities quickly. The company describes it as a more affordable, highly capable alternative to larger AI security systems.
The model will initially be available to governments and trusted partners through CodeMender, Google’s security-focused coding agent. Because Gemini 3.5 Flash Cyber is designed for speed and lower cost, CodeMender can call on it repeatedly to support rapid analysis and remediation.
Why this matters
Cybersecurity teams often face more vulnerabilities than they can manually review, and powerful AI systems can be expensive to operate at scale. A cheaper specialized model could make continuous vulnerability detection and patching more practical for organizations protecting critical systems.
- Faster defense: AI agents can help scan, reason about, and patch weaknesses more quickly.
- Lower cost: A Flash-based model may make repeated security checks more economical.
- Real-world focus: Google is deploying the model through CodeMender for trusted users rather than presenting it only as a research demo.
