Google's most powerful model Gemini 4 Carbon is officially launched, with a security team uncovering a brand-new zero-day vulnerability in just two hours.

Beating AI Insight Breaking News: Google has officially made Gemini 4 Carbon available to general users. For the past two weeks, only a small number of cybersecurity teams had access to the tool; now all paid developers can call 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 supported at this time. Google also shared a real-world use case: its subsidiary cybersecurity firm Wiz used Carbon to audit two large software service providers, identifying a brand-new zero-day vulnerability in under two hours and helping the companies patch it. Google noted that such vulnerability research typically takes weeks in the past. However, Wiz used the cybersecurity-specific version Carbon for Cyber, which still requires an application to the Fairwind program for access. The version now open to general users is the general-purpose edition. The API’s launch price is $2 per million input tokens and $10 per million output tokens, matching Argon’s pricing. The discount is only valid until November 30, after which prices will double. Google said Carbon is suited for complex programming, in-depth debugging, and scientific research tasks, as it requires more tokens for repeated reasoning and verification. Argon remains the recommended option for most daily work.
