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

Elon Musk's xAI is rolling out Grok 4 after the previous model, Grok 3, made a series of antisemitic posts praising Hitler. Mike Isaac, technology reporter for the New York Times, joins CBS News to discuss.

This is the smartest AI in the world,” Musk said. He did not mention the chatbot’s viral posts praising Hitler and calling itself “MechaHitler.”

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.

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

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

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.
