Google's launch post for Gemini 4 Argon, dated Oct 13, 2026, says Google AI Ultra and Google AI Pro subscribers get it in the Gemini app, and the same two plans in AI Mode in Search. Free accounts aren't on that list, and the Gemini app's Oct 13 release note names the same two plans. The post's browser-tab title reads "now available for everyone"; the body doesn't extend that to the app's free tier.
Developers and enterprises get Argon through the API in AI Studio and the Gemini platform, and Ultra subscribers can also use it in Google Antigravity, Google's coding tool. Google says it ranks #1 on the Vals Index, a benchmark of finance, coding, legal and tax work.
On Nov 9, 2026 the Gemini app sat at No. 9 on Apple's US free-app chart.
What the plans cost in the app
In-app purchase prices on the US App Store, as of Nov 9, 2026:
| Plan | Price | Storage listed |
|---|---|---|
| Google AI Plus | $4.99 | 400 GB |
| Google AI Pro | $19.99 | 5 TB |
| Google AI Ultra | $199.99 | 30 TB |
The listing also sells a 100 GB storage tier at $1.99. Google's Argon post doesn't mention Plus. The App Store description says Plus, Pro, Ultra and Workspace users get Gemini Omni video generation, and calls Argon and Omni "our latest models".
