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.

Elon Musk’s artificial intelligence company said its Grok chatbot had also undergone a code update that caused it to share antisemitic messages this week.

Elon Musk faces backlash after Grok AI made antisemitic remarks. Critics say Musk’s tweaks to the model steer it from fact-based responses.
