Elon Musk’s artificial intelligence (AI) company xAI apologized to users for antisemitic posts authored by its chatbot Grok, pinning the blame on an update after conducting an investigation.

AI apologized on Saturday after its chatbot Grok posted antisemitic and violent messages earlier this week. The firm said an update to the system caused the bot to pull ideas from user content on X, even when those posts included extremist views.
