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.

Grok, the chatbot built by Musk’s start-up xAI, is integrated into X, the social media platform formerly known as Twitter.
