The latest version of Grok for iOS (version 1.1.18) comes with two companions — an anime girl called Ani and a red panda called Rudi.

As for why Grok was consulting Musk’s posts when asked about controversial topics, the company wrote, “The model reasons that as an AI it doesn’t have an opinion but knowing it was Grok 4 by xAI, searches to see what xAI or Elon Musk might have said on a topic to align itself with the company.”

The companions have their own X accounts, because of course they do. Ani's bio states, "Smooth, a little unpredictable—I might dance, tease, or just watch you figure me out. Let’s keep it chill… or not." Meanwhile, Rudy's just says, "The Only Pet in Grok Companion."

AI explained why Grok 4 seemed to search for Elon Musk's opinions when asked about some hot-button topics.

The announcement comes just days after Grok generated antisemitic responses and praised Hitler, which were later deleted.

When Elon Musk’s Grok AI chatbot began spewing out antisemitic responses to several queries on X last week, some users were shocked.

The important thing to remember here is just that a single sentence can fundamentally change the way these systems respond to people, said Alex Mahadevan of the Poynter Institute, discussing the irritable actions of big language models (LLMs) such as Grok.
