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.

We are aware of posts made by Grok and are actively working to remove the inappropriate posts,” Musk's company said.
