At the launch of Grok-4, the xAI presenters prompted the chatbot to predict the World Series. After 4.5 minutes, it had an answer.

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."

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

On Wednesday night, Elon Musk unveiled xAI's latest flagship models Grok 4 and Grok 4 Heavy via livestream, just one day after the company's Grok chatbot began generating outputs that featured blatantly antisemitic tropes in responses to users on X.

X eventually deleted many of the obscene posts. Hours later, on Wednesday, X CEO Linda Yaccarino resigned from the company after just two years at the helm, though it wasn’t immediately clear whether her departure was related to the Grok issue.

We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts,” xAI said in a statement, adding that it “has taken action to ban hate speech before Grok posts on X.

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

The Polish deputy prime minister is asking the EU to investigate Grok, the AI chatbot integrated into the X social media platform.

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