Gemini 4 Argon will open to Google AI Ultra subscribers and paid API customers first

In its Gemini 4 Argon announcement, Google said the broader rollout starts with Google AI Ultra subscribers and paid API customers, with timing described only as "soon." For now only trusted testers and cyber defenders in the Fairwind Program can use it. A post relaying "coming soon, starting with AI Ultra subscribers" from @Google circulated, with replies saying the Ultra plan will finally be worth it.

Pricing is as reported yesterday: $2 per million input tokens and $10 per million output tokens during the launch period, with a 95% discount on cached input, rising to $4 and $20 afterward. Google has not said when Argon reaches the Gemini app.
