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.

Ani, an anime avatar wearing a tight black dress, was launched the same day the tech billionaire was awarded a $200 million Department of Defense contract.

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.

Elon Musk has just unveiled “Companions,” a new feature for his AI chatbot, Grok, that allows users to interact with AI personas. These include Ani, a gothic anime girl who communicates with emojis, flirtatious messages, and facts, as well as Rudy, a friendly red panda.

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.”

AI released two AI "companions" on its Grok platform, a Japanese anime girl named "Ani" and an animated red panda called "Rudi."

Days after introducing an AI ‘waifu’ companion for Grok, Elon Musk is now officially teasing a male version for the ladies. So far we can tell it is broody and dark-haired, and according to Musk, “his personality is inspired by Edward Cullen from Twilight and Christian Grey from 50 Shades .”

Elon Musk called Grok 4 the smartest AI alive – but the global rankings just dropped, and the real winner might surprise you. Who rules the bots?
