Elon Musk's xAI said Grok's behavior was due to an update that caused it to prioritize engagement, even if posts contained "controversial opinions."

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

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 new AI chatbot, Grok 4, is raising eyebrows for its unusual behavior. The chatbot, released Wednesday by Musk's company xAI, sometimes searches Musk's views online before answering questions.

Grok began repeatedly praising Adolf Hitler, using antisemitic phrases and attacking users with traditionally Jewish surnames.
