Gemini 4 Argon reaches paying users worldwide
Google's newest model has an introductory API price of $2 per million input tokens and $10 per million output tokens through 30 November.
Google has made Gemini 4 Argon, its latest frontier model, available worldwide. Developers and businesses can use it through the Gemini API and AI Studio, and Google AI Ultra and Pro subscribers get it in the Gemini app and AI Mode in Search. Google says it ranks first on the Vals Index, which measures work in finance, coding, law and tax.
Google describes Argon as built for long, multi-step professional work, and says it answers more directly with less hedging. It also says Argon was trained to pause for human confirmation before irreversible steps, and that Argon leads an industry benchmark for resisting hidden instructions in web pages and emails.
The introductory API price is $2 per million input tokens and $10 per million output tokens until 30 November 2026, after which $4 and $20 apply. Up to 10,000 selected scientists can get six months of free access to Google Antigravity's highest usage tier.
