 "title": "Google releases Gemini 3.8 Flash Cyber for trusted defenders, emphasizing automated patching",
 "lane": "defense",
 "kind": "tool-release",
 "summary": "Google introduced Gemini 3.8 Flash Cyber, a cybersecurity-tuned model with more permissive cyber mitigations, available only to trusted defenders through a new Fairwind Program. Google says it prioritized vulnerability fixing over exploitation and reports 47.2% pass@1 on Collinear's CWE-Bench patching benchmark, over 70% on an internal 20-language discovery benchmark, and 2.6 times more correct Chrome patches than larger commercial models.",
 "whyItMatters": "It is a gated, defense-oriented model release that foregrounds patching metrics rather than offensive capability.",
