Fairwind Program

Google has made Gemini 4 Carbon generally available to developers, enterprises, scientists, and consumers, positioning it as its strongest frontier model for cybersecurity capabilities and long-horizon agentic workflows. Carbon sits above Gemini 4 Argon and targets extreme tasks such as complex multi-step coding, debugging, and open-ended scientific research, while Argon remains the default for most software engineering and knowledge work. Carbon was previously released to select cybersecurity defenders through the Fairwind Program.
