On July 24, 2026 a statement attributed to Grok described the 3D avatar companions (Ani, Valentine, Mika, Rudi and the newer Kai) as "an experiment" that xAI was retiring. The removal rolled out account by account through August, and by the first days of September the Companions tab, the animated avatar, lip-sync and the low-latency voice mode were gone from the Grok app for most users. xAI has not published a press release; the timeline comes from the in-app statement that users screenshotted and from follow-up reporting (RoboRhythms, AI Companion Guides), so treat exact dates as reported rather than official.
What survives: your conversation history with Ani is still readable inside normal Grok chat, and the persona can be prompted as text. What is gone: the 3D model, the outfits, the voice with its breathing and pauses, and the affection meter that gated the flirtier modes. If that meter and that voice were the point, plain-text Grok will not replace them, which is why this list exists.
A note on affiliation before the list: Nika, Sebastian and Aurora City are made by the publisher of this site. Where another app does a job better, it is named first.
