Google limits Gemini 4 Argon to trusted cyber defenders

Google has unveiled Gemini 4 Argon, its latest frontier AI model. According to chief AI architect Koray Kavukcuoglu, the model delivers frontier performance in complex software engineering, enterprise knowledge work such as legal and finance, and cybersecurity defense. Access is currently restricted to a select group of trusted cyber defenders, and Google says it is engaged in the U.S. government's voluntary process for pre-release model access while gradually expanding availability.
