Elon Musk's new AI chatbot, Grok 4, is raising eyebrows for its unusual behavior. The latest version of Elon Musk's artificial intelligence chatbot Grok is echoing the views of its billionaire creator, so much so that it will sometimes search online for Musk's stance on an issue before offering up an opinion.

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.

Elon Musk unveiled the newest edition of xAI's flagship AI model, Grok, late Wednesday night in a livestream video that touted Grok 4's prowess at topping benchmark scores.Why it matters: xAI is in an accelerating race with OpenAI,

According to the Financial Times, xAI plans to spend $18 billion on expanding its compute infrastructure. The company trains its models using a supercomputer called Colossus that is located in Memphis. Earlier this year, Musk stated that xAI plans to increase the number of graphics cards in the system from 200,000 to 1 million.

Finnish e-motor startup Donut Lab raised €25 million ($29.2 million) in a seed funding round led by Risto Siilasmaa, the founder of cybersecurity company WithSecure (formerly F-Secure). Risto has also joined Donut Lab’s board.

Grok 4 was released approximately one day after xAI addressed and deleted inappropriate posts by the chatbot on X, which included antisemitic remarks.
