1. Google Releases Gemini 3.8 Flash and a Cyber-Specialized Variant

Google. Gemini 3.8 Flash is positioned as Google’s workhorse model for autonomous agents and multi-step software engineering, with a companion 3.8 Flash Cyber variant tuned for vulnerability detection and automated patching. Google reports the model exceeds a 70% success rate across 20 programming languages on an internal benchmark, scores 47.2% pass@1 on CWE-Bench for vulnerability patching, and improves prompt-injection robustness on Gray Swan evaluations. Introductory pricing is $0.75 per million input tokens and $3.75 per million output tokens through December 31, 2026, doubling to $1.50 and $7.50 after that. The base model is available in Google AI Studio, Android Studio, the Gemini API, the Gemini app, Search, Sheets, and Gemini Enterprise; the Cyber variant is gated behind an application. Source

2. Fairwind Program Gates Cyber Models Behind Vetted Access

Google. Fairwind is a limited-access program pairing Gemini 3.8 Flash Cyber with Google’s CodeMender technology so participants can autonomously find and repair software vulnerabilities, producing verified deployment-ready patches rather than findings alone. Access is restricted to government agencies and national cyber authorities, critical infrastructure operators in healthcare, telecom, energy and finance, and core technology platforms with large downstream user bases. Google says over 650 partners are participating globally. Source
