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.

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.”

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

After the president appeared to mimic an Asian accent, according to social media users, one person asked Musk's AI chatbot, Grok, to assess his behavior.

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