Gemini 4 Argon reaches general availability, two weeks after its cyber-defender-only debut

Per Sundar Pichai's own announcement, Gemini 4 Argon is now available globally today for developers and enterprises on the paid tier of the Gemini API and Gemini platform, for Google AI Ultra subscribers in Google Antigravity, and for Ultra and Pro subscribers in the Gemini app and Search. This closes the gap between Argon's limited, government/cyber-defender-only debut and a genuine public release.

Google launches Gemini 4 Argon, a frontier model for coding, enterprise work and cybersecurity defense

Per Google's own announcement, Argon is built to sustain deep reasoning across complex, long-horizon workflows, with an industry-leading 1M-token output limit, and targets real-world software engineering, legal/finance knowledge work, and autonomous cybersecurity vulnerability patching. Demis Hassabis framed it as "rolling out responsibly starting with government and trusted cyber defenders," with wider availability — starting with paid API customers and Google AI Ultra subscribers — to follow "as soon as possible." No public benchmark report has shipped alongside it yet.
