Gemini 3.8 Flash Cyber

by Google

Released 1 days after Gemini 3.8 Live · Announcement · All Google releases

Gemini 3.8 Flash Cyber is a post-training version of Gemini 3.8 Flash that Google tailored for cybersecurity work. It shares the 3.8 Flash foundation, keeps the 1,048,576 token context window and 65,536 token output ceiling, accepts text, images, audio, video and PDFs, and returns text. Thinking, function calling, structured output, code execution and Google Search grounding are supported. Google positions it for defenders: discovering vulnerabilities in large codebases, triaging findings and writing correct patches, the kind of long, tool-driven agent loops where the Flash tier's speed and price matter. It replaces the earlier 3.5 Flash Cyber. Access is restricted by Google. The model is generally available on Vertex only behind an allowlist, through Google's Fairwind program for government authorities, critical infrastructure operators and software maintainers, and its use falls under the Gemini Cyber section of Google's service terms. On Opper it is listed in the cyber access group: organizations can request access, and calls are refused until access is granted.
