# Google announces new AI model for detecting security vulnerabilities Gemini 3.5 Flash Cyber offers a cost-effective alternative to large, expensive security models. - **Source:** [The Verge (theverge.com)](https://www.theverge.com) - **Published:** 2026-07-21 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/4a7177d0-e5dd-4588-aadd-84c330d42abd ## Google's new security-focused AI model Google unveiled Gemini 3.5 Flash Cyber, a new AI security model designed as a cost-efficient alternative to larger, more expensive systems. The model specializes in rapidly identifying code vulnerabilities and security flaws in software applications. ## Integration with CodeMender The new model will work with Google's security-focused coding agent CodeMender. Optimized for high-speed, low-cost multiple invocations, the system can scan more code paths to uncover potential security threats efficiently. ## Competitive benchmark performance Google claims its model achieved competitive results against 'significantly larger models' in CyberGym benchmark tests. It identified 55 unique issues in V8 JavaScript Engine, outperforming rival solutions from competitors. ## Challenging Anthropic's Mythos Positioned as a competitor to Anthropic's expensive Mythos model, Google's solution initially targets governments and trusted partners. Microsoft's recent massive Patch Tuesday highlights the growing importance of AI-powered security solutions. ## Budget-friendly options Google also announced 3.5 Flash-Lite as its 'most cost-effective' model and upgraded versions of 3.6 Flash. The company aims to capture market share by offering solutions for different budgets and security needs. ## AI arms race in cybersecurity Google's move underscores the increasing importance of AI in cybersecurity. With competitors like China's Z.ai developing similar models, the industry is poised for intensified competition in AI-powered security solutions. ## Sources covering this story - https://www.theverge.com/tech/968572/google-gemini-flash-cyber-ai-security-model — --- _Summary written by Brifing from the original reporting.
