What is changing?
After two weeks of limited cybersecurity testing, Google is opening Gemini 4 Carbon to developers, enterprises, scientists, and consumers. The model is available to all paying developers and enterprise customers through the paid Gemini API tier in Google AI Studio and through Gemini for business. It is also rolling out to Google AI Ultra subscribers in Google Antigravity, the Gemini app, and AI Mode in Search. Introductory pricing is $2 per million input tokens and $10 per million output tokens.
Google describes Carbon as its strongest model for complex coding, long-running agentic workflows, dense-document analysis, scientific reasoning, and cyber defense. A new /swarm preview in Antigravity turns one prompt into a trackable team of agents. The published performance and safety results combine provider testing with selected external evaluations; production teams should retest cost, latency, failure modes, and security boundaries on their own workloads.
