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.

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

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.
