•Gemini 3.5 Flash Cyber is designed for rapid identification and patching of vulnerabilities.
•The model will initially be available to governments and trusted partners only.
•Testing showed Gemini 3.5 Flash Cyber outperformed larger models on the CyberGym benchmark.

On July 21, 2026, Google introduced Gemini 3.5 Flash Cyber, a new AI model designed to identify and patch software vulnerabilities efficiently. This model is part of a limited-access pilot program available only to governments and trusted partners through CodeMender. Gemini 3.5 Flash Cyber is built on the Gemini 3.5 Flash framework and is touted as a cost-effective alternative to larger models like Anthropic's Mythos. The model was tested against the CyberGym benchmark, achieving competitive results by identifying unique vulnerabilities in software such as the V8 JavaScript Engine. This launch reflects Google's strategic push into the cybersecurity space amid increasing competition from rivals like Anthropic and OpenAI. Alongside this, Google also released Gemini 3.6 Flash and 3.5 Flash-Lite, focusing on improved performance and reduced costs. The new models aim to provide developers with efficient tools for high-volume workloads and cybersecurity tasks.
