Hello @70708851 , Thanks for using Microsoft Q&A Platform.
A commitment pricing tier is added/applied to a particular resource that is selected by you on the Azure portal. As we know while creating a resource, we generally select region and the pricing tier. Once your resource is created (or already existing resource is available) you can change your pricing from pay-as-you-go, to a commitment plan.
Coming to your question, you will have to select specific resource that applies 2,000 hrs/month for 1600 USD. Means only one of those resources(endpoint) get that pricing tier as we select the resource first then the pricing tier is updated. You can purchase a commitment plan by updating your Azure resource as mentioned here:
I hope this helps. Please go through this documentation to know more about purchasing a commitment tier plan: https://learn.microsoft.com/en-us/azure/ai-services/commitment-tier#purchase-a-commitment-plan-by-updating-your-azure-resource
I hope this helps.
