In a late-night announcement, X owner Elon Musk unveiled the new Grok 4 chatbot. Here's everything you need to know about it.

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.

X CEO Linda Yaccarino announced she was stepping down from her position a day after the company's Grok artificial intelligence chatbot went haywire and began calling itself "MechaHitler." Yaccarino's departing message was positive and did not mention Tuesday's scandal.

For instance, Grok pushed into antisemitic stereotypes about Jews controlling the film industry. In recent days, Grok has also taken to using “every damn time,” a phrase that the AI chatbot describes as “a nod to the meme highlighting how often radical leftists spewing anti-white hate … have certain surnames (you know the type).”

A Turkish court has blocked access to Grok, the artificial intelligence chatbot developed by the Elon Musk-founded company xAI, after it generated responses that authorities said included insults to President Tayyip Erdogan.
