Google on Tuesday released its Gemini 4 Carbon artificial intelligence model to developers, enterprises, scientists and consumers.
The company said Carbon is its strongest model, designed for complex tasks such as multi-step software coding, debugging and open-ended scientific research that require deep reasoning.
The model is available through the application programming interface in Google AI Studio and Gemini for business. Google AI Ultra subscribers can access it in the Gemini application, AI Mode in Search and Google Antigravity. Google set an introductory price of $2 per million input tokens and $10 per million output tokens. After Nov. 30, 2026, the price will increase to $4 per million input tokens and $20 per million output tokens.
Google is also previewing a feature in Google Antigravity called /swarm, which turns a single prompt into a coordinated team of agents. The company said early testers used Carbon to uncover software vulnerabilities, build 3D games and mathematically prove cryptographic code.
