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

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."

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.

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

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

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.

The xAI chatbot will arrive on Tesla vehicles by “next week at the latest,” according to Elon Musk, who previously said in January that it was “coming soon.” This wasn’t mentioned during last night’s live demo of Grok 4.

Poland's Deputy PM Krzysztof Gawkowski calls on the European Commission to investigate Elon Musk’s chatbot over hate speech violations and threats to public safety.

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

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.
