Elon Musk has launched xAI’s Grok 4—calling it the “world’s smartest AI” and claiming it can ace Ph.D.-level exams and outpace rivals such as Google’s Gemini and OpenAI’s o3 on tough benchmarks

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.

Most advertisers on X are choosing to remain silent on their future plans and relationship with the company after Grok went on a racist and antisemitic spree.

Musk's announcement comes hours after xAI debuted its latest flagship AI model, Grok 4. The 54-year-old discussed the recent innovation during a nearly hour-long livestream shared on xAI's X page, during which he did not mention the chatbot's integration into Tesla vehicles.

France is investigating Elon Musk’s X and a member of parliament, Éric Bothorel, is criticizing Grok's content.

The tech billionaire unveiled its latest version, Grok 4, which he claims is "smarter than almost all graduate students, in all disciplines, simultaneously."

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.”

TechnologyAdvice's Grant Harvey provides a deep dive on Grok 4, the "new" model from Elon Musk's AI company xAI.

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