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.

The AI chatbot Grok, which is produced by Elon Musk’s xAI, wrote numerous antisemitic social media posts Tuesday after the artificial intelligence company released a revamped version of it over the weekend. The posts ranged from alleging "patterns" about Jewish people to praising Hitler.

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