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.

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.
