Gemini 3.5 Flash Cyber

Gemini 3.5 Flash Cyber is Google's first cybersecurity-specialized model, fine-tuned from 3.5 Flash to find, validate, and patch vulnerabilities. Inside CodeMender's multi-agent architecture, it reaches competitive performance on CyberGym against much larger models like Mythos at a fraction of the cost. But the restrictions are severe: it runs exclusively within CodeMender, available only to governments and trusted partners via a limited-access pilot with no public API, no published benchmark numbers, and no timeline for broader release. For the vast majority of developers, this model is simply inaccessible — watch for access expansion.
