Credit packs
One balance. Every Grok model.
Every pack uses the same rate: 1,000 credits per dollar. Larger packs add capacity, not a hidden discount, so the two-times cost rule stays consistent.

Typical turn estimates use 2,000 input tokens and 1,000 output tokens. Longer conversation history increases the input charge.

Pricing Q&A
Know what happens before you spend.
What do the first three free questions include?
They use Grok Build 0.1, the default basic model. A free question is counted only after a response is returned. Advanced models and additional questions require a positive credit balance.
How are credits calculated?
One credit represents $0.001 of retail usage. The retail token rate is two times the current OpenRouter provider rate. Input and output are priced separately, so a long answer can cost more than a short one even when the prompt is identical.
Why are advanced models locked?
Advanced models have different inference costs and are reserved for credit users. Grok Build 0.1 remains the low-cost default so a visitor can test the product before choosing a pack.
Do unused credits expire or roll over?
Credits are stored on your account and do not expire during this test release. Test payments have no cash value. Refund and dispute rules will be finalized before live payments open.
Is a real payment processed on this page?
No real charge is made while the checkout is in Stripe test mode. Use Stripe's 4242 4242 4242 4242 test card with any future expiry date and CVC. Do not enter a real card during testing.
Is the current credit limit secure?
Yes. A signed Stripe webhook is the only path that can grant purchased credits. Duplicate events and Checkout Sessions are ignored, and every successful grant is recorded in the account ledger.
When do purchased credits appear?
Stripe returns you to this page after payment, but the return page does not grant credits. The balance updates only after the signed payment webhook is verified and committed, which normally takes a few seconds.
