Extra Usage Pack: Purchasing Additional Usage

After your subscription credits run out, you can continue sending requests with your Extra Usage Pack (Extra Usage) balance, without waiting for your credits to refresh. This feature is available only to subscribers, and Kimi on the web and Kimi Code share the same Extra Usage Pack credits—top up once and use it on both. For the full terms, see the Extra Usage Pack Top-up Agreement.

Top-up entry points

  • Top up from the main site: Go to the Kimi Subscription page, scroll to the “Extra Usage Credit Pack” section at the bottom → select a top-up amount → complete payment.
  • Top up from the Kimi Code console: When either your weekly credit or 5-hour credit usage exceeds 80%, a “Buy Extra Usage Pack” button will appear on the progress bar card. Click it to go to the Kimi subscription page and complete your purchase.

Enable and manage

After you turn on “Extra Usage Credit Pack,” the system will automatically deduct from your Extra Usage Pack balance when your subscription credits run out. Click “Settings” in the section to enable a monthly spending cap and set the maximum amount you can spend this month. The progress bar shows your Extra Usage Pack consumption for the current month in real time.

Billing and rules

  • Billing: Charges are based on actual usage—the more content read and generated, and the more complex the task, the higher the cost. Balances are shown in RMB, and rates are subject to the prices displayed on the platform. Extra Usage Pack pricing is similar to the official API pricing of the Kimi Open Platform. If you use a large volume, upgrading your subscription is usually more cost-effective.
  • Deduction priority: Time-limited credits, such as subscription credits, are deducted first, and the Extra Usage Pack is deducted last as a fallback. Once enabled, even if your subscription credits run out, your Extra Usage Pack balance can be used seamlessly, so tasks will not be interrupted or fail with an error.
  • Spending control: You can enable “Monthly spending cap” in Settings to set the maximum amount that can be spent from your Extra Usage Pack this month. If you do not enable it, there is no cap.
  • Validity and stacking: The balance does not expire and can be accumulated. After your subscription expires, the balance can still be used, but you cannot top up during the expired period. You need to renew your subscription before topping up again.
  • Refunds: In general, balances are non-refundable, non-transferable, and cannot be redeemed for cash.

Billing examples (for scale only; actual charges are subject to the platform): a simple request, such as “recommend a rock song,” costs about RMB 0.03; a complex multi-step task, such as “plan a one-week self-driving itinerary from Chengdu to western Sichuan,” costs about RMB 1.6. Top-up limits: the minimum per top-up is RMB 25; up to 10 top-ups per day, with a daily total of RMB 3,000; the balance cap is RMB 10,000.

Check usage

  • Kimi web / App: Settings → Subscription and invoices → My Credits.
  • Kimi Code console: After enabling the Extra Usage Pack, log in to the console to view your balance and usage.
  • Kimi Code CLI: Enter /usage in the command line to check directly.

Do Kimi on the web and Kimi Code use the same Extra Usage Pack wallet?

Yes. Both share the same Extra Usage Pack credits, so one top-up works for both.

Which is deducted first: the Extra Usage Pack or subscription credits?

Time-limited credits, such as subscription credits, are deducted first. The Extra Usage Pack is deducted as a fallback only after all time-limited credits have been used up.

Can I continue using Kimi after reaching a credit limit or being rate-limited?

Yes. After you enable the Extra Usage Pack, subscription limits no longer apply. When any credit limit is reached, usage will switch seamlessly to your Extra Usage Pack balance, with no task interruption. Only the Extra Usage Pack balance will be deducted, and your membership credit refresh will not be affected.

Can unused balance be carried over to next month?

Yes. The balance does not expire and can be accumulated. After your subscription expires, you can still use the balance, but you cannot top up during the expired period.

Does the Extra Usage Pack support enterprise plans?

Not currently.

Will my balance be refunded after I close my account?
