Google DeepMind releases Gemini 3.5 Flash Cyber security model

Introducing Gemini 3.5 Flash Cyber

Google DeepMind released Gemini 3.5 Flash Cyber, fine-tuned from 3.5 Flash to find, verify and patch vulnerabilities quickly. With multiple calls, it approaches larger models on benchmarks such as CyberGym.

Why it matters: It reports how a lightweight security model performs on several benchmarks and inside Google's own codebase, so readers can judge the cost-benefit for vulnerability discovery.
