# Google announces new AI security model for vulnerability detection Gemini 3.5 Flash Cyber offers a cost-effective alternative to larger, more expensive models. - **Source:** [The Verge](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/f897cd7a-d138-403b-8011-80843fb1faaf ## Google's AI-powered security move Google unveiled a new AI security model called Gemini 3.5 Flash Cyber. This model aims to provide a more cost-effective alternative compared to large, expensive systems. Specializing in quickly detecting code vulnerabilities, the model will initially be available to governments and trusted partners. ## Advantages over competitor models Gemini 3.5 Flash Cyber offers significant advantages over competitors like Anthropic's Mythos 5. While Mythos reportedly costs twice as much as Claude Opus 4.8, Google's model promises similar performance at lower costs. As companies like Microsoft adopt Mythos, Google is intensifying competition in this space. ## CodeMender integration Google's security-focused coding agent CodeMender will work integrated with the new model. The system can invoke 3.5 Flash Cyber multiple times at high speed and low cost, enabling scanning of more code paths. This approach promises more comprehensive results in vulnerability detection. ## Performance metrics Google stated its model demonstrated 'competitive performance' against 'significantly larger models' on the CyberGym AI cybersecurity benchmark. Detecting 55 unique issues in the V8 JavaScript Engine, the model outperformed competitors. It also discovered 10 new vulnerabilities that other models missed. ## Other Gemini updates The company also announced that Gemini 3.6 Flash offers improvements in coding and multimodal performance, while 3.5 Flash-Lite was introduced as the series' 'most cost-effective' model. These updates are part of Google's diversification strategy in the AI field. ## AI race in cybersecurity Google's move underscores the growing importance of AI-based solutions in cybersecurity. Microsoft's adoption of Mythos and claims from competitors like China's Z.ai demonstrate intense industry competition. Google's model has potential to stand out in this race with its cost advantages. ## 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.
