The AI chatbot Grok, which is produced by Elon Musk’s xAI, wrote numerous antisemitic social media posts Tuesday after the artificial intelligence company released a revamped version of it over the weekend. The posts ranged from alleging "patterns" about Jewish people to praising Hitler.

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."
