Google's Gemini 4 Carbon Is Now Widely Available Around the World

Google is making Gemini 4 Carbon accessible to more users after its initial release to select cybersecurity defense companies in late October. The company says the model can be used for the most complex tasks, such as multi-step coding and scientific research, while Gemini 4 Argon remains the better choice for most ordinary and even the majority of software engineering tasks.

Access and pricing

Gemini 4 Carbon is now available in Google AI Studio and Gemini for business. Google AI Ultra subscribers paying $100 a month for membership will also get access to Carbon within the Gemini app, AI Model in Search and Antigravity, Google's agentic software development and AI coding platform. Google is launching Carbon at an introductory price of $2 per million input tokens and $10 per million output tokens, with those rates set to double at the end of November.

Intended use

Gemini 4 Carbon promises a significant leap in AI coding and cybersecurity, as well as in scientific research. Argon was the first Gemini 4 model and is considered less advanced than Carbon. Since Carbon was designed to test the limits of a model's intelligence, it is best used for multi-step coding, scientific research and discovery, and other more complex tasks. Google said Carbon had helped its first users uncover zero-day vulnerabilities in a short span of time and has made advances in protein structure prediction, which is necessary for developing medications.

Scientist program

Google is giving 10,000 scientists free access to Carbon for six months to help with their research. The company has already onboarded thousands, and the initiative would presumably help train its models in turn.
