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

The lack of public response from advertisers stands in stark contrast to their response in 2023 following an antisemitic post from Elon Musk.

Grok 4 aligns its answers with Elon Musk's when it comes to controversial issues, users have discovered shortly after the company launched the new model.

Grok 4 has a favorite source on some hot-topic issues, citing Elon Musk's opinions without being instructed to do so.

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.”

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.

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.
