Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

The unusual behavior of Grok 4, the AI model that Musk's company xAI released late Wednesday, has surprised some experts.

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.”

XAI's Grok 4 AI chatbot launched Wednesday appears to consult Elon Musk's views when asked its opinion on some controversial matters.

Elon Musk released the newest artificial intelligence model from his company xAI on Wednesday night. In an hour-long public reveal session, he called the model, Grok 4, “the smartest AI in the world” and claimed it was capable of getting perfect SAT scores and near-perfect GRE results in every subject,

A former professor and the founder of his own AI company, Howard noticed that if he asked Grok about the Israeli-Palestinian conflict, the chatbot seemed to cross-check Elon’s tweets before regurgitating an answer.

At the launch of Grok 4, the xAI presenters prompted the chatbot to predict the World Series. The AI said the Dodgers had a 21.6% chance of winning.

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.
