1. Log in to the ModelArts management console and choose AI Application Management > AI Applications > Edge Subscriptions from the left navigation pane.
2. On the Edge Subscriptions page, select a model in the Unpaid status, and click Buy in the Operation column.
3. On the displayed page, set Advanced Settings and Required Duration and click Next.
4. On the Confirm tab page, check the configurations and click Submit to create a notebook instance.
5. On the payment page, confirm the amount to be paid, select a payment method, and click Confirm Payment.

   After the payment is complete, you can click the link on the page to quickly return to the management console of the AI service (for example, Face Recognition) for which the model is subscribed or the Subscribed Models page.
