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.

Elon Musk’s xAI is leaning into its over-the-top AI “companions,” which the company debuted Monday.In the last day, the company has given several indications that it would be further investing in its companions product, which allows users to interact with stylized and animated characters that are powered by Grok, its AI chatbot.

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.

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.”

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

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.

Elon Musk has named xAI's new AI companion "Ani," triggering a new meme coin frenzy around the latest update of Grok, Grok 4.
