Google's most powerful model, Gemini 4 Carbon, officially opens, security team uncovers brand-new zero-day vulnerability in 2 hours.

Beating AI News Flash: Google has officially opened Gemini 4 Carbon to general users. For the past two weeks, only a few cybersecurity teams were able to try it; now all paid developers can access it via API. Google AI Ultra users can also use it in Gemini, Search AI Mode, and Antigravity, while Pro and free users are not yet supported.

Google also disclosed a real-world use case. Its cybersecurity company Wiz used Carbon to inspect two large software service providers and discovered brand-new zero-day vulnerabilities in under two hours, helping the companies fix them. Google says this kind of vulnerability research typically took weeks in the past.

However, Wiz used the specialized cybersecurity version, Carbon for cyber, which still requires applying to the Fairwind program for access. What is being opened to general users this time is the general-purpose version.

The API launch price is $2 per million tokens for input and $10 for output, the same as Argon. The discount lasts only until November 30, after which the price doubles.

Google says Carbon is suited for complex programming, deep debugging, and scientific research tasks, and will spend more tokens on repeated reasoning and verification. For most everyday work, Argon is still recommended.
