Gemini 3.8 Flash Cyber

The cybersecurity-tuned sibling of Gemini 3.8 Flash, introduced by Google DeepMind on Sep 2, 2026 in the same launch. It shares the same foundational intelligence as Gemini 3.8 Flash but ships with a more permissive set of mitigations for defensive security work, and is available only to trusted defenders — government authorities, critical-infrastructure operators, and software maintainers — through the new Fairwind Program. Google reports frontier-level autonomous vulnerability discovery (surpassing Gemini 3.5 Flash Cyber and much larger frontier models on the CyberGym benchmark), a success rate exceeding 70% on an internal real-world vulnerability benchmark spanning 20 programming languages, and 47.2% pass@1 on the external CWE-Bench patching benchmark (on the Pareto frontier versus a leading frontier model at 47.8%, at far lower cost). Google is already using it internally: the Chrome Security team reports 2.6x more correct patches than the best larger commercial models, and its Cloud Vulnerability Research team found a critical foundational vulnerability in under two hours. Keeps a 1M-token context and multimodal input with text output; prioritizes vulnerability fixing over offensive capability. Not publicly token-billed (trusted-access only), so no list price is recorded. Benchmark figures are vendor-reported.
