You can choose the yearly/monthly, pay-per-use, or one-off payment billing mode.

Billing Items

The billing items of MetaStudio include virtual avatars.

For details, see Table 1.

On the MetaStudio console, click Buy Resource on the Overview page to purchase required resources. For details, see Purchase Guide.

**Table 1** Billing items
Category	Billing Item	Description	Billing Mode
Virtual avatar	Image modeling	You are charged based on the number of created virtual avatar images. Each time a virtual avatar image is created, one quota will be deducted from your purchased resource package. CAUTION: If you delete the image asset created using a purchased resource package with auto-renewal enabled, you need to cancel auto-renewal first. A message will be displayed in the warning dialog box when you delete an image asset. Perform operations as prompted. Assume that you purchase a one-year image modeling resource package: You can create only one image asset within the validity period (one year). After one year, the purchased resource package will be frozen. If you do not renew after the package is frozen, the image asset created using the package will also be frozen and unavailable. If the grace period and retention period expire after the one-year validity period, the billed resources will be deleted, along with the image asset created using these resources.	Yearly
	Voice modeling	You are charged based on the number of created voices. Each time a virtual avatar voice is created, one quota will be deducted from your purchased resource package. CAUTION: If you delete the voice asset created using a purchased resource package with auto-renewal enabled, you need to cancel auto-renewal first. A message will be displayed in the warning dialog box when you delete a voice asset. Perform operations as prompted. Assume that you purchase a one-year voice modeling resource package: You can create only one voice asset within the validity period (one year). After one year, the purchased resource package will be frozen. If you do not renew after the package is frozen, the voice asset created using the package will also be frozen and unavailable. If the grace period and retention period expire after the one-year validity period, the billed resources will be deleted, along with the voice asset created using these resources.	Yearly
	Video production	You are charged based on the duration of a virtual avatar video. To enable pay-per-use billing, go to the My Resources area of the MetaStudio console. Click Enable Pay-per-Use in the Virtual avatar video production card. In the Information dialog box displayed, agree to the agreement and click OK. Click OK to enable pay-per-use billing. Note: The duration of a composited video is expressed in second. The actual charging will convert the duration from seconds to minutes. The value is accurate to two decimal places and the last digit is rounded off. Even if a composited video is frozen due to inappropriate content, the video production fees are still charged.	Pay-per-use
	Livestreaming	The subscription entry is not open. You can use virtual avatar livestreaming only when: you have submitted a service ticket for enabling virtual avatar livestreaming; the administrator has allocated livestreaming resources to you. Note: If the number of concurrent livestreaming tasks exceeds the allocated quota, the excess tasks cannot be executed due to insufficient resources.	Allocated by the administrator
	Intelligent interaction	You can purchase multiple dialogs. Each dialog is free of charge within the validity period of the yearly/monthly subscription. Note: The actions of a virtual avatar for intelligent interaction are generated after training based on the video of its human counterpart. The virtual avatar (1080p) features precise lip sync and seamless fusion with the background. Intelligent interaction supports multiple knowledge bases (in both Chinese and English) to meet different needs. Equipped with trained avatar and voice models, MetaStudio's interactive virtual avatars can use knowledge bases to interact with users in real time. The more dialogs you purchase, the more interactive dialogs can be performed with a virtual avatar simultaneously. Resources will become unavailable after the validity period expires, so we recommend enabling auto-renewal. If the number of concurrent intelligent interaction tasks exceeds the allocated quota, the excess tasks cannot be executed due to insufficient resources.	Yearly/Monthly

Billing Modes

You can choose either the pay-per-use or yearly billing mode.

Pay-per-use: You pay as you go and just pay for what you use. In each billing cycle, the fee is calculated by multiplying the actual usage of each resource by its unit price. Then, this fee is taken from your account balance.
Yearly/Monthly: a prepaid billing mode. You pay in advance for a subscription term, and in exchange, you get a discounted rate. The longer the subscription term, the bigger the discount. This mode is a good option for long-term, stable services.

Resource Validity Period

Package billing starts from the effective time after the order is paid. You can use the resources in the package within the validity period. With pay-per-use billing, you are charged based on the actual resource usage and there is no validity period limit.

You can view the expiration time of the resource package in Overview > My Resources of the MetaStudio console, as shown in Figure 1.

Figure 1 Resource list

Renewal

The yearly billing mode allows for renewal before the quota is used up. To renew the subscription, go to the Renewals page. If the renewal fails, the fee will be deducted from the account balance.

Unsubscription

Yearly packages for virtual avatar image modeling and voice modeling cannot be unsubscribed.
On the service overview page, if pay-per-use billing is enabled, you can disable it.
- Enabling pay-per-use billing: Click Enable Pay-per-Use in the resource card. In the dialog box displayed, agree to the agreement. Click OK.
- Disabling pay-per-use billing: Click Disable in the resource card. In the dialog box displayed, click OK.

Expiration and Arrears

Arrears: Prepaid package resources do not expire. With pay-per-use billing, fees are deducted based on each billing item in its billing cycle. Insufficient account balance will cause fee deduction of the previous billing cycle to fail, making your account in arrears. If your account is in arrears, your cloud service resources will enter a grace period and probably a retention period. For more information, see Resource Suspension and Release.
You can view the arrears information of your account and pay the arrears in Billing Center.

Complete the renewal during the retention period. If the service is in arrears and enters the retention period, the service will be unfrozen after the renewal.
Service expiration: Pay-per-use resources do not expire. If a prepaid resource package expires, the remaining resources will be cleared. Since then, you will be billed for subsequent resource usage on a pay-per-use basis.
