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 AI chatbot Grok, which is produced by Elon Musk’s xAI, wrote numerous antisemitic social media posts Tuesday after the artificial intelligence company released a revamped version of it over the weekend. The posts ranged from alleging "patterns" about Jewish people to praising Hitler.

Earlier today, Grok showed me how to tell if someone is a “good scientist,” just from their demographics. For starters, according to a formula devised by Elon Musk’s chatbot, they have to be a white, Asian, or Jewish man.
