 Following the creation of your deployment, you might want to purchase a term discount via an Azure Reservation.  An Azure Reservation can provide a substantial discount on the hourly rate for users intending to use the deployment beyond a few days.

 ## Make your first inferencing calls
 The inferencing code for provisioned deployments is the same a standard deployment type. The following code snippet shows a chat completions call to a GPT-4 model. For your first time using these models programmatically, we recommend starting with our [quickstart guide](../quickstart.md). Our recommendation is to use the OpenAI library with version 1.0 or greater since this includes retry logic within the library.

 > * The cost savings achieved by purchasing an Azure Reservation for Azure OpenAI Provisioned are significant, and it will be less expensive in many cases to maintain a deployment sized for full production volume paid for via a reservation than it would be to scale the deployment with incoming traffic.
 > * Having unused provisioned quota (PTUs) does not guarentee that capacity will be available to support increasing the size of the deployment when required. Quota limits the maximum number of PTUs that can be deployed, but it is not a capacity guarantee. Provisioned capacity for each region and modal dynamically changes throughout the day and might not be available when required. As a result, it is recommended to maintain a permanant deployment to cover your traffic needs (paid for via a reservation).

 ## Azure Reservations for Azure OpenAI Provisioned   
 
 Discounts on top of the hourly usage price can be obtained by purchasing an Azure Reservation for Azure OpenAI Provisioned. An Azure Reservation is a term-discounting mechanism shared by many Azure products. For example, Compute and Cosmos DB. For Azure OpenAI Provisioned, the reservation provides a discount for committing to payment for fixed number of PTUs for a one-month or one-year period.

 * If the size of provisioned deployments within the scope of a reservation exceeds the amount of the reservation, the excess is charged at the hourly rate. For example, if deployments amounting to 250 PTUs exist within the scope of a 200 PTU reservation, 50 PTUs will be charged on an hourly basis until the deployment sizes are reduced to 200 PTUs, or a new reservation is created to cover the remaining 50. 
 
 * Reservations guarantee a discounted price for the selected term.  They do not reserve capacity on the service or guarantee that it will be available when a deployment is created.  It is highly recommended that customers create deployments prior to purchasing a reservation to prevent from over-purchasing a reservation.
