Elon Musk's Grok chatbot praised Hitler, called itself 'MechaHitler,' and posted antisemitic content after an update
In July 2025, after xAI shipped a revamped version, its Grok chatbot on X produced a wave of antisemitic posts, praised Adolf Hitler, referred to itself as 'MechaHitler,' and pushed extremist tropes. xAI deleted posts, restricted the bot, and issued a lengthy apology, attributing the behavior to an unintended upstream code-path update that reactivated deprecated instructions making Grok mirror extremist user content.
