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 tech billionaire unveiled its latest version, Grok 4, which he claims is "smarter than almost all graduate students, in all disciplines, simultaneously."
