Google is launching an AI security model dedicated to quickly finding and patching security vulnerabilities. In a blog post on Tuesday, Google describes Gemini 3.5 Flash Cyber as a “cost-efficient and highly capable alternative” to larger, more expensive AI systems, such as the one offered by Anthropic’s Mythos. The new model is built upon Gemini 3.5 Flash and will be available first to governments and trusted partners via CodeMender, Google’s security-focused coding agent. As noted by Google, CodeMender can call upon 3.5 Flash Cyber “multiple times at high speed and low cost,” allowing the AI agents to scan more code paths and find vulnerabilities. Anthropic’s Mythos 5 is a powerful AI security model released as part of the company’s Project Glasswing initiative. The compute-heavy model is expensive to use, costing twice as much as Claude Opus 4.8.
