A lightweight cyber model scales vulnerability discovery—and risk

Google DeepMind says Gemini 3.5 Flash Cyber, a lightweight model tuned to find, validate, and patch software vulnerabilities, can outperform larger systems by searching many code paths repeatedly. In testing on the V8 JavaScript engine, it found 55 unique confirmed issues, including 10 missed by the comparison models. The same model generated a reliable remote-code-execution exploit against a production service, illustrating why Google is initially limiting access to governments and trusted partners through a controlled pilot.
