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.

Musk wrote in an X post on Monday that AI companions are now available in the Grok app for "Super Grok" subscribers who pay $30 per month.

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

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.

Companions in Grok is currently available only to the SuperGrok Heavy subscribers who pay $300 (roughly Rs. 25,700) a month.

Grok began repeatedly praising Adolf Hitler, using antisemitic phrases and attacking users with traditionally Jewish surnames.
