The tech billionaire unveiled its latest version, Grok 4, which he claims is "smarter than almost all graduate students, in all disciplines, simultaneously."

In a livestream with xAI colleagues, the billionaire entrepreneur described current AI systems as “primitive” and not for “serious” commercial use.
