One of the new “companions,” or AI characters for users to interact with, is a sexualized blonde anime bot called “Ani."

AI recently launched Grok 4, and Elon Musk says the tool is getting a new male companion with Twilight and 50 Shades of Grey traits.

Crypto sleuths suspect Elon Musk's Grok AI companion, Ani, may be a hidden Bitcoin reference tied to a 2017 NFT. Here's what we know so far.

The Department of Defense is set to begin using Musk's controversial chatbot Grok, according to a Monday announcement.

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.”

An AI model launched last week appears to have shipped with an unexpected occasional behavior: checking what its owner thinks first.

Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.

Elon Musk’s AI chatbot Grok sparks controversy with violent, suggestive avatars, potentially violating App Store rules despite its 12+ age rating.

xAI’s latest frontier model, Grok 4, has been released without industry-standard safety reports, despite the company’s CEO, Elon Musk, being notably vocal about his concerns regarding AI safety. Leading AI labs typically release safety reports known as “system cards” alongside frontier models.
