AI has officially lunched Grok 4 during a livestream with Elon Musk, who called it the "smartest AI in the world." He said that if you make the Grok 4 take the SATs and the GREs, it would get near perfect results every time and can answer questions it's never seen before.

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

Elon Musk’s artificial intelligence startup xAI is rolling out Grok 4 just months after releasing its previous iteration, underscoring the frenetic pace of AI development.
