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 news comes alongside the U.S. Department of Defense’s announcement of $200 million contracts awarded to xAI, Anthropic, Google and OpenAI for AI implementation.

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

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.

Musk believes that the most successful AIs will be the ones that maximize things that matter to conscious beings; things that feel good, are rewarding, or extend life. In Musk’s view, that means aligning AI systems with long-term human flourishing,

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