Azure AI Search regions list
This article identifies the cloud regions in which Azure AI Search is available. It also lists which premium features are available in each region.
- AI enrichment refer to skills and vectorizers that make internal calls to Azure AI and Azure OpenAI. AI enrichment requires that Azure AI Search coexist with an Azure AI multi-service account in the same physical region. The following tables indicate whether Azure AI is offered in the same region as Azure AI Search.
- Availability zones are an Azure platform capability that divides a region's data centers into distinct physical location groups to provide high-availability, within the same region.
We recommend that you check Azure AI Studio region availability and Azure OpenAI model region availability for the most current list of regions for those features.
Also, if you're using Azure AI Vision 4.0 multimodal APIs for image vectorization, it's available on a more limited basis. Check the Azure AI Vision region list for multimodal embeddings and be sure to create both your Azure AI multi-service account and Azure AI Search service in one of those supported regions.
Note
Higher capacity partitions became available in selected regions starting in April 2024. A second wave of higher capacity partitions released in May 2024. If you're using an older search service, consider creating a new search service to benefit from more capacity at the same billing rate as before. For more information, see Service limits
