Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

Days after Grok praises Hitler, Musk touts the chatbot as smarter than PhDs in 'every subject' and debuts the SuperHeavy Grok subscription.

Elon Musk’s live demo of Grok 4, the latest big-ticket model from his AI startup, began with high-intensity music, claims of a “ludicrous rate of progress,” and a lot of chatter on X about Grok’s scandal-filled week.

Authorities said the chatbot generated responses insulting the strongman president, modern Turkey's founder Mustafa Kemal Ataturk and religious values.

Grok, the chatbot developed by Elon Musk’s AI firm xAI, is doing rather less chatting, after making racist comments.

A change to Grok’s internal instructions, or system prompt, is leading users to accuse Elon Musk’s AI of a renewed rightward tilt. The new instructions tell it to assume some media information is biased.

Elon Musk's Grok AI chatbot blamed DOGE for Texas flood deaths and shared an antisemitic trope, days before Grok 4's release.
