Google Unveils Gemini 3.8 Flash and a Cybersecurity Specialist Model
Flash Cyber autonomously finds and patches vulnerabilities, with government access rolling out via a new Fairwind Program.
Google DeepMind released two new models: Gemini 3.8 Flash, which the company calls its most intelligent yet with gains in software engineering and multi-step agentic reasoning, and Gemini 3.8 Flash Cyber, a specialized version built for vulnerability detection and autonomous patching.
On the CyberGym benchmark, Flash Cyber leads at finding weaknesses without human help, and in tests across Google Chrome's codebase it produced 2.6 times more valid fixes than prior approaches while generating deployable patches in minutes inside an organization's own cloud environment.
Google is rolling out access to Flash Cyber through a new Fairwind Program, giving national cyber authorities and operators of critical infrastructure like telecom and energy networks trusted access to help secure their systems. Flash 3.8 is available now in Google's Antigravity coding tool and via API in Google AI Studio; Cursor added support the same day.
