Google DeepMind launches Gemini 3.5 Flash Cyber for security
Google DeepMind has introduced Gemini 3.5 Flash Cyber, a specialised AI model for cybersecurity. The model is designed to detect and validate software vulnerabilities efficiently, aiming to provide defenders with scalable tools against new AI-driven threats.
What happened?
Google DeepMind has announced the launch of Gemini 3.5 Flash Cyber. This is an AI model optimised for cybersecurity tasks, built on the Gemini 3.5 Flash architecture. The model is specifically trained to find, validate, and assist in remediating software vulnerabilities. It is integrated into CodeMender, Google's automated code security agent.
Key facts
”Google DeepMind har meddelat Gemini 3.5 Flash Cyber, en specialiserad cybersäkerhetsmodell byggd på Gemini 3.5 Flash-arkitekturen. Designad för att hitta, validera och åtgärda mjukvarusårbarheter effektivt, syftar modellen till att ge försvarare ett skalbart och kostnadseffektivt”
Why it matters
The model aims to improve the ability to detect vulnerabilities in software. By offering a scalable and cost-effective tool, it can help counter the increasing threats from AI-driven attacks. The model outperforms mainline Flash models in vulnerability detection and has shown competitive results in benchmark tests.
Who is affected?
Cybersecurity experts, software developers, and organisations managing large codebases are affected. Initially, access is limited to a pilot programme for governments and trusted partners. In the long term, a wider launch will occur, which could affect all organisations that develop software.
What else you should know
In internal testing, 3.5 Flash Cyber has been used to detect vulnerabilities in production environments, including remote code execution and memory corruption vulnerabilities. The model has shown better results compared to Gemini 3.5 Flash and 3.6 Flash in finding critical vulnerabilities in complex codebases such as Chrome and Safari.
