Elon Musk's AI company, xAI, has launched SuperGrok, a new paid subscription service for its Grok chatbot. The service offers three tiers: SuperGrok Lite at $10 per month, providing access to Grok 3.5; a standard plan at $30 per month, and SuperGrok Heavy for $300 per month, catering to heavy users. An enterprise plan is also available at $30 per user monthly. Free and basic users will continue with Grok 3 but face stricter limits on query volume and features.
