Google’s Gemini 4 Carbon is now widely available around the world

Google has widened access to Gemini 4 Carbon, which was first released to selected cybersecurity companies in late October. The expansion matters because Google says the model can handle complex work, including multi-step coding and scientific research, while Gemini 4 Argon remains better for most routine software engineering.

Google says Carbon helped early users uncover zero-day vulnerabilities and improved protein structure prediction, which is relevant to medicine development. It is available through Google AI Studio and Gemini for business, and Google AI Ultra subscribers paying $100 a month can use it in the Gemini app, AI Mode in Search and Antigravity. Google is also offering six months of free access to 10,000 scientists, with thousands already enrolled.
