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.

Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.

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