Google Has Not Confirmed Gemini 4 Carbon, Despite Claims of a New Benchmark Leader

Claims that Google has announced Gemini 4 Carbon and that it leads Artificial Analysis’s latest ranking are not supported by the available primary sources. Google’s published materials describe Gemini 4 Argon, while Artificial Analysis’s v5 results list Argon at 50 and Claude Opus 5.5 at 58; neither source names Carbon as a released model or ranking leader.
