Gemini 4 Argon, Google’s newest model, is now in the Gemini app, but only for AI Pro and Ultra subscribers. Google’s October 13 announcement names those two tiers and no others. Free users and AI Plus subscribers are not mentioned.
Google first opened Argon to a set of trusted cyber defenders through its Fairwind Program. We covered that limited release at the time. This is the first time the model has reached the consumer Gemini app.
Gemini 4 Argon is for AI Pro and Ultra subscribers
Google says Argon brings stronger reasoning and better performance on complex tasks. Google is direct about who gets it.
“Google AI Pro and Ultra subscribers can now access Gemini 4 Argon and give Gemini tasks to get more done.”
That is Google’s own wording, from its Gemini app blog post.
Google says the update is available starting October 13. Its post does not name any countries or regions.
According to The Verge, Pro and Ultra subscribers also get Argon in AI Mode in Search. The Verge adds that it is unclear when, or whether, Argon will reach Plus subscribers or free users.
What this means for free Gemini users
Nothing in Google’s announcement says Argon is coming to the free tier. That fits a pattern from the past few weeks. Free users lost the Flash and Pro model choices on October 9. The free tier now shows only an Auto option instead of a model picker.
Paid-first launches are not new either. Gemini 3.8 Flash also arrived for paying users only. If you are on the free tier or AI Plus, plan on Argon staying behind a Pro or Ultra subscription until Google says otherwise.
Coding upgrades and Antigravity on Mac
Google says Argon brings major improvements in coding. To make switching between chat and code easier, Google has put Antigravity’s agentic coding interface directly inside the Gemini app for macOS. That is a Mac app feature, and Google’s post describes no Android equivalent.
The Verge also reports that Ultra subscribers get Argon on Antigravity, Google’s agentic development platform.
API pricing for developers
The Verge reports an introductory API price of $2 per million input tokens and $10 per million output tokens. Google’s announcement post does not list that price. Google has not said, in the material we reviewed, how long the introductory rate will last.
