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.

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.

Elon Musk's xAI faced internal backlash after Grok's antisemitic posts. Workers demanded answers — and one said they would quit.

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."

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