Plan and manage costs for Azure Cognitive Services
This article describes how you plan for and manage costs for Azure Cognitive Services. First, you use the Azure pricing calculator to help plan for Cognitive Services costs before you add any resources for the service to estimate costs. Next, as you add Azure resources, review the estimated costs. After you've started using Cognitive Services resources (for example Speech, Computer Vision, LUIS, Text Analytics, Translator, etc.), use Cost Management features to set budgets and monitor costs. You can also review forecasted costs and identify spending trends to identify areas where you might want to act. Costs for Cognitive Services are only a portion of the monthly costs in your Azure bill. Although this article explains how to plan for and manage costs for Cognitive Services, you're billed for all Azure services and resources used in your Azure subscription, including the third-party services.
Cost analysis in Cost Management supports most Azure account types, but not all of them. To view the full list of supported account types, see Understand Cost Management data. To view cost data, you need at least read access for an Azure account. For information about assigning access to Azure Cost Management data, see Assign access to data.
Estimate costs before using Cognitive Services
Use the Azure pricing calculator to estimate costs before you add Cognitive Services.
As you add new resources to your workspace, return to this calculator and add the same resource here to update your cost estimates.
For more information, see Azure Cognitive Services pricing.
Understand the full billing model for Cognitive Services
Cognitive Services runs on Azure infrastructure that accrues costs when you deploy the new resource. It's important to understand that additional infrastructure might accrue cost. You need to manage that cost when you make changes to deployed resources.
Costs that typically accrue with Cognitive Services
Typically, after you deploy an Azure resource, costs are determined by your pricing tier and the API calls you make to your endpoint. If the service you're using has a commitment tier, going over the allotted calls in your tier may incur an overage charge.
Additional costs may accrue when using these services:
When you create resources for QnA Maker, resources for other Azure services may also be created. They include:
Costs that might accrue after resource deletion
After you delete QnA Maker resources, the following resources might continue to exist. They continue to accrue costs until you delete them.
Using Azure Prepayment credit with Cognitive Services
You can pay for Cognitive Services charges with your Azure Prepayment (previously called monetary commitment) credit. However, you can't use Azure Prepayment credit to pay for charges for third party products and services including those from the Azure Marketplace.
As you use Azure resources with Cognitive Services, you incur costs. Azure resource usage unit costs vary by time intervals (seconds, minutes, hours, and days) or by unit usage (bytes, megabytes, and so on). As soon as use of a Cognitive Service (or Cognitive Services) starts, costs are incurred and you can see the costs in cost analysis.
When you use cost analysis, you view Cognitive Services costs in graphs and tables for different time intervals. Some examples are by day, current and prior month, and year. You also view costs against budgets and forecasted costs. Switching to longer views over time can help you identify spending trends. And you see where overspending might have occurred. If you've created budgets, you can also easily see where they're exceeded.
To view Cognitive Services costs in cost analysis:
- Sign in to the Azure portal.
- Open the scope in the Azure portal and select Cost analysis in the menu. For example, go to Subscriptions, select a subscription from the list, and then select Cost analysis in the menu. Select Scope to switch to a different scope in cost analysis.
- By default, cost for services are shown in the first donut chart. Select the area in the chart labeled Cognitive Services.
Actual monthly costs are shown when you initially open cost analysis. Here's an example showing all monthly usage costs.
- To narrow costs for a single service, like Cognitive Services, select Add filter and then select Service name. Then, select Cognitive Services.
Here's an example showing costs for just Cognitive Services.
In the preceding example, you see the current cost for the service. Costs by Azure regions (locations) and Cognitive Services costs by resource group are also shown. From here, you can explore costs on your own.
You can create budgets to manage costs and create alerts that automatically notify stakeholders of spending anomalies and overspending risks. Alerts are based on spending compared to budget and cost thresholds. Budgets and alerts are created for Azure subscriptions and resource groups, so they're useful as part of an overall cost monitoring strategy.
Budgets can be created with filters for specific resources or services in Azure if you want more granularity present in your monitoring. Filters help ensure that you don't accidentally create new resources that cost you additional money. For more about the filter options when you when create a budget, see Group and filter options.
Export cost data
You can also export your cost data to a storage account. This is helpful when you need or others to do additional data analysis for costs. For example, finance teams can analyze the data using Excel or Power BI. You can export your costs on a daily, weekly, or monthly schedule and set a custom date range. Exporting cost data is the recommended way to retrieve cost datasets.
