This week, Musk's xAI company unveiled the 'Companion' feature on the Grok platform, leveraging Grok's four core models. Among the inaugural characters are Ani, a girl embodying a gothic aesthetic, and 'Bad Rudy,' a charming cartoon baby panda. To access this feature, users must subscribe to the SuperGrok service, priced at $30 per month, with hints of additional, highly personalized virtual characters on the horizon.
