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.

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 ‘maximally truth-seeking’ chatbot checks Musk’s stance on topics around Israel and Palestine, abortion, and immigration.

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.”
