What are Azure AI services?

Azure AI services help developers and organizations rapidly create intelligent, cutting-edge, market-ready, and responsible applications with out-of-the-box and pre-built and customizable APIs and models. Example applications include natural language processing for conversations, search, monitoring, translation, speech, vision, and decision-making.


As of July 2023, Azure AI services encompass all of what were previously known as Cognitive Services and Azure Applied AI Services. There are no changes to pricing. The names Cognitive Services and Azure Applied AI continue to be used in Azure billing, cost analysis, price list, and price APIs. There are no breaking changes to application programming interfaces (APIs) or SDKs.

Most Azure AI services are available through REST APIs and client library SDKs in popular development languages. For more information, see each service's documentation.

Pricing tiers and billing

Pricing tiers (and the amount you get billed) are based on the number of transactions you send using your authentication information. Each pricing tier specifies the:

  • maximum number of allowed transactions per second (TPS).
  • service features enabled within the pricing tier.
  • cost for a predefined number of transactions. Going above this number will cause an extra charge as specified in the pricing details for your service.


Many of the Azure AI services have a free tier you can use to try the service. To use the free tier, use F0 as the SKU for your resource.
