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.

We are aware of posts made by Grok and are actively working to remove the inappropriate posts,” Musk's company said.

The antisemitic posts from Grok came days after Elon Musk wrote on X that the chatbot had been improved "significantly."
