Elon Musk on Wednesday teased a forthcoming male Grok companion from xAI, which already offers an anime waifu named Ani and a red panda named Rudi.

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

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.

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.

Elon Musk’s artificial intelligence start-up xAI has apologized after its AI Chatbot Grok published a series of antisemitic messages on X.

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.

Internal docs show xAI paid contractors to "hillclimb" Grok's rank on a coding leaderboard above Anthropic's Claude.
