Google introduced Gemini 4 Argon on October 13. Developers can use the paid Gemini API tier; Pro and Ultra subscribers get access in the Gemini app and AI Mode, while Ultra subscribers can use it in Antigravity. “For everyone” does not mean a free, unrestricted rollout.
Introductory API pricing is $2 per million input tokens and $10 per million output tokens. Google's footnote says that becomes $4 and $20 after November 30, 2026.
Google reports more agentic code submissions and fewer rollbacks in its own engineering teams. Those are company-reported results, not a promise about your project. A sensible comparison measures completed tasks, corrections and total cost, rather than token prices alone.
