About this release

What is 3.5 Flash Cyber?

Gemini 3.5 Flash Cyber is a specialized cybersecurity model built on top of the 3.5 Flash base and fine-tuned specifically for finding, validating, and patching software vulnerabilities. It enables agents like CodeMender to explore far more code paths efficiently due to its speed and low cost, outperforming the base Flash models on benchmarks such as CyberGym and internal Google evaluations for discovering unique issues in complex codebases like Chrome and V8.
