Gemini 4 Argon is still limited to a select few: Google starts with cybersecurity partners
Google designed its new model for complex development tasks that require sustained work.
As of Sep 30, 2026, Gemini 4 Argon is available only to a small group of Google's cybersecurity partners, according to Axios.
A new top-tier model. Before Argon, Google released smaller, cheaper Flash models. The company has now added a new flagship generation of Gemini, designed for software development among other uses.
