xAI Grok API Pricing FAQ

01 How does xAI Grok API pricing work?

The xAI Grok API uses pay-as-you-go token-based pricing under the Pay-as-you-go (Grok 4, Grok 4 fast, Grok Code Fast) plan with no monthly commitment.

02 What is SuperGrok and how does it differ from the Grok API?

SuperGrok is a consumer subscription to grok.com priced at approximately $30/month or $300/year, offering enhanced chatbot access with features like DeeperSearch, Think Mode, and unlimited image generation. The Grok API is a separate developer product with pay-as-you-go token-based pricing for programmatic access and is distinct from any consumer subscription.

03 Can I access Grok through an X Premium subscription instead of the API?

Yes, Grok is available within the X platform to X Premium and Premium+ subscribers (Premium+ reported at $22/month), which unlocks higher usage quotas and advanced features. However, this is a consumer access path, not developer API access. The xAI Grok API for programmatic use is a separate product with pay-as-you-go token pricing.
