 You can save money on Azure OpenAI provisioned throughput by committing to a reservation for your provisioned throughput units (PTUs) usage for a duration of one month or one year.

 The Azure OpenAI reservation size should be based on the total provisioned throughput units that you consume via deployments. Reservation purchases are made in one provisioned throughput unit increments.
 
-For example, assume that your total consumption of provisioned throughput units is 100 units. You want to purchase a reservation for all of it, so you should purchase 100 of reservation quantity.
+For example, assume you deployed 100 units of the Provisioned Regional deployment type and 50 units of Provisioned Global deployment type. In this example, you should purchase a Provisioned Managed Regional reservation for a quantity of 100 units and a Provisioned Managed Global reservation for a quantity of 50 units to cover all of your deployed PTUs.
 
 > [!CAUTION]
 > Capacity availability for model deployments is dynamic and changes frequently across regions and models. To prevent buying a reservation for more PTUs than you can use, create deployments first. Then buy the reservation to cover the PTUs you deployed. This best practice ensures that you maximize the reservation discount and helps to prevent you from purchasing a term commitment that you can’t fully use.

 ### Reservation discount application
 
 The application of the Azure OpenAI reservation is based on an hourly comparison between the reserved and deployed PTUs. The sum of deployed PTUs up-to the amount reserved are covered (paid for) via the reservation, while any deployed PTUs in excess of the reserved PTUs get charged at the hourly, pay-as-you-go rate. There are a few other points to keep in mind:
 
 - PTUs for partial-hour deployments are pro-rated based on the number of minutes the deployment exists during the hour. For example, a 100 PTU deployment that exists for only 15 minutes of an hour period is considered as a 25 PTU deployment. Specifically, 15 minutes is 1/4 of an hour, so only 1/4 of the deployed PTUs are considered for billing and reservation application during that hour.
-- Deployments are matched to reservations based on the reservation scope before the reservation is applied. For example, a reservation scoped to a single subscription only cover deployments within that subscription. Deployments in other subscriptions are charged the hourly, pay-as-you-go rate, unless they're covered by other reservations that have them in scope.
+- Deployments are matched to reservations based on the reservation scope before the reservation is applied. For example, a reservation scoped to a single subscription only covers deployments within that subscription. Deployments in other subscriptions are charged at the hourly pay-as-you-go rate, unless they're covered by other reservations that have them in scope.
 
 The reservation price assumes a 24x7 deployment of the reserved PTUs. In periods with fewer deployed PTUs than reserved PTUs, all deployed PTUs get covered by the reservation, but the excess reserved PTUs aren't used. These excess reserved PTUs are lost and don't carry over to other periods.
 
 ### Discount examples
 
 The following examples show how the Azure OpenAI reservation discount applies, depending on the deployments.
 
-- **Example 1** - A reservation that's exactly the same size as the deployed units. For example, you purchase 100 PTUs on a reservation and you deploy 100 PTUs. In this example, you only pay the reservation price.
-- **Example 2** - A reservation that's larger than your deployed units. For example, you purchase 300 PTUs on a reservation and you only deploy 100 PTUs. In this example, the reservation discount is applied to 100 PTUs. The remaining 200 PTUs, in the reservation will go unused, and won't carry forward to future billing periods.
-- **Example 3** - A reservation that's smaller than the deployed units. For example, you purchase 200 PTUs on a reservation and you deploy 600 PTUs. In this example, the reservation discount is applied to the 200 PTUs that were used. The remaining 400 PTUs are charged at the pay-as-you-go rate.
-- **Example 4** - A reservation that's the same size as the total of two deployments. For example, you purchase 200 PTUs on a reservation and you have two deployments of 100 PTUs each. In this example, the discount is applied to the sum of deployed units.
+**Example 1** - A regional reservation that's exactly the same size as the regional deployed units. For example, you purchase 100 PTUs on a regional reservation and you deploy 100 regional PTUs. In this example, you only pay the reservation price.
+
+**Example 2** - A global reservation that's larger than your global deployed units. For example, you purchase 300 PTUs on a global reservation and you only deploy 100 global PTUs. In this example, the global reservation discount is applied to 100 global PTUs. The remaining 200 PTUs, in the global reservation will go unused, and won't carry forward to future billing periods.
+
+**Example 3** - A data zone reservation that's smaller than the data zone deployed units. For example, you purchase 200 PTUs on a data zone reservation and you deploy 600 data zone PTUs. In this example, the data zone reservation discount is applied to the 200 data zone PTUs that were used. The remaining 400 data zone  PTUs are charged at the pay-as-you-go rate.
+
+**Example 4** - A regional reservation that's the same size as the total of two regional  deployments. For example, you purchase 200 regional PTUs on a reservation and you have two deployments of 100 regional PTUs each. In this example, the discount is applied to the sum of deployed units.
