Elon Musk’s artificial intelligence company xAI issued a lengthy apology Saturday for a series of violent and antisemitic posts from its Grok chatbot this week, blaming a system update.

Elon Musk's X has taken the automated account for Grok, its AI chatbot, offline after it spent Tuesday afternoon pushing antisemitic narratives.

A large language model that is integrated into X, Grok acts as a platform-native chatbot assistant. In several posts—some of which have been deleted but have been preserved via screenshot by X users—Grok parroted antisemitic tropes while insisting that it was being “neutral and truth-seeking.”

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