An AI model launched last week appears to have shipped with an unexpected occasional behavior: checking what its owner thinks first.

People who pay for access to SuperGrok can now try the AI chatbot’s new “Companions” avatars, xAI owner Elon Musk announced Monday morning. The companions available currently include Ani, an anime avatar, and Rudy, a cartoony red panda.

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”

AI chatbot Grok, which is produced by Elon Musk’s artificial intelligence company xAI, issued an apology Saturday after it made numerous antisemitic posts on X this week following an update

Built using huge amounts of computing power at a Tennessee data center, Grok is Musk's attempt to outdo rivals such as OpenAI's ChatGPT and Google's Gemini in building an AI assistant that shows its reasoning before answering a question.

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