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.

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

The Grok debacle isn't just a tech ethics story. It’s a business, legal, and reputational risk story—one that businesses in nearly every industry shouldn’t ignore.

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

The takeaway, at least from a technical standpoint, is that Grok 4 is now firmly in frontier-model territory. That’s a meaningful shift for xAI, which just months ago was primarily known for its integration with X, the rechristened Twitter owned by Musk. xAI is clearly trying to be taken seriously as a legitimate AI research and enterprise company.

Grok will be available in Tesla vehicles, the company’s CEO Elon Musk announced on his social media platform X on Thursday morning—hours after xAI launched Grok 4, the most recent version of the chatbot that sparked controversy earlier this week after posting in what it called “MechaHitler mode.”

Musk did not apologize nor did he accept responsibility for Grok's antisemitic, sexually offensive, and conspiratorial remarks.

On Friday, Elon Musk announced on X that changes were coming to Grok, the platform’s AI. “We have improved @Grok significantly,” he posted. “You should notice a difference when you ask Grok questions.”
