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.

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.

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.”

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

Grok's recent update was part of Musk's broader effort to position Grok as an "anti-woke" alternative to AI chatbots like ChatGPT.

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