Google Opens Gemini 4 Argon to Developers and Businesses Worldwide

What happened

Google said in a press release on Tuesday, October 13, that Gemini 4 Argon is now generally available to developers and businesses worldwide. Paying customers can access it through the Gemini API (AI Studio and the Gemini platform); Google AI Pro and Ultra subscribers can use it in the Gemini app and AI Mode in Search, while the Antigravity coding tool is available to Ultra subscribers.

The rollout marks a major expansion since the model's first announcement on September 30, when access was limited to a small set of trusted cybersecurity partners through the Fairwind Program. Google said the program will now open to hundreds of additional partners, who receive a version of Argon without its cyber guardrails. (Reuters, Oct 13)
