Google Begins Global Gemini 4 Carbon Rollout With API Access

Google began a global rollout of Gemini 4 Carbon on Nov. 11, opening API access to developers and enterprise customers for a model designed to reason through extended, complex work.

The model is being made available worldwide through Google AI Studio's Gemini API and Gemini Enterprise. Developers can connect to it through the API, while businesses can access the model through Google's enterprise offering.

Ultra subscribers can also use Gemini 4 Carbon in Antigravity, Gemini App and Search AI Mode, giving users on that plan access through three Google products.

Google designed the model for long-running tasks that require sustained reasoning. Its intended applications include complex software engineering, cybersecurity and scientific discovery, spanning technical work and research use cases.

Google released Gemini 4 Carbon in late October and initially made it available to some cybersecurity defenders. The Nov. 11 rollout expands access beyond that early group, bringing API and enterprise availability to users worldwide.
