Elon Musk's xAI has launched 'Companions' for its Grok AI chatbot, including an anime avatar named Ani and a red panda named Rudy. SuperGrok subscribers can access these avatars, with Ani featuring an 'NSFW' mode with lingerie. Users currently need to enable Companions in settings, but Musk says accessibility will be improved soon. While initially intended for paying users, some free users have also reported access. The launch has already generated NSFW content related to the avatars on X, highlighting the platform's content moderation challenges.
