GOOGLE'S STRONGEST MODEL IS OPEN TO EVERYONE — AND THE PRICE DOUBLES DECEMBER 1

Google made Gemini 4 Carbon generally available on November 10 to paying developers through the Gemini API, to enterprises, and to Google AI Ultra subscribers in Antigravity, the Gemini app and AI Mode in Search. Google calls Carbon its strongest model, built for cybersecurity work and long-horizon agentic jobs across software engineering and scientific reasoning. It had been restricted to vetted cyber defenders through the Fairwind Program since October 28.

The catch is the price: $2 per million input tokens and $10 per million output tokens only through November 30 — from December 1 the same tokens cost $4 and $20. There is no free-tier access.
