Elon Musk's xAI said Grok's behavior was due to an update that caused it to prioritize engagement, even if posts contained "controversial opinions."

The unusual behavior of Grok 4, the AI model that Musk's company xAI released late Wednesday, has surprised some experts.

Following Grok 4’s recent controversy involving antisemitic messages, the AI chatbot is under fire for consulting Elon Musk’s X posts when answering some questions.

Some X users suddenly became the subject of violent ideations by xAI’s flagship chatbot.

The release comes months after the AI startup launched its previous iteration, suggesting an ongoing lightning pace of AI development.
