Gemini 4 Argon begins rolling out in Gemini app and Antigravity, but only if you pay

What's happening

Google has released Gemini 4 Argon and begun rolling it out inside the Gemini app and Antigravity, but access is gated behind paid tiers. Google says Argon delivers "frontier reasoning and improved performance across complex workflows" and is being used to modernize massive codebases, speed model inference, and accelerate breakthroughs in quantum computing and life sciences. Developers get 50 percent discounted API rates through November. At the same time Google is positioning Gemini as an enterprise agent that can plan and execute tasks across business apps, and Gemini Pro features are now limited to Google AI Pro and AI Ultra subscribers.

Why it's trending

Multiple product moves and pricing limits landed at once, making Argon availability and paid tiers the immediate conversation.
