3. Detailed Rules by Account Type

3.1. Prepaid Account

    • Calculated based on the corresponding pricing

    • Deducted directly from the current user credit quota

• When quota = 0:

  • All models will be disabled

  • Users must purchase additional quota to continue usage

---

3.1.2. User Credit Expiration

• User credits are valid for 1 year

• The validity period is calculated from the most recent top-up date

When user credits expire:

• Users can:

  • Recover user credits from the Billing page

After recovery:

• Previous user credit quota will be lost

Recovery Expiration

• If more than 7 days have passed since user credit expiration:

  • Users must:

    • Reactivate billing

    • Purchase additional user credits if they wish to continue using the service

It is recommended that users estimate usage in advance and proactively top up credits to avoid service interruptions due to exhausted quota or expired credits.
