- [Semantic ranking](semantic-search-overview.md) depends on models hosted by Microsoft. These models are available in specific regions.

- [AI enrichment](cognitive-search-concept-intro.md) 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](/azure/ai-services/multi-service-resource) in the same physical region. The following tables indicate whether Azure AI is offered in the same region as Azure AI Search.

## Features subject to regional availability
21+
22+
| Feature | Availability |
23+
|---------|--------------|
24+
| [Extra capacity](search-limits-quotas-capacity.md#service-limits) | Higher capacity partitions became available in selected regions starting in April 2024 with a second wave following in May 2024. Currently, there are just a few regions that *don't* offer higher capacity partitions. If you're using an older search service, create a new search service to benefit from more capacity at the same billing rate. To check existing capacity, [find your search service](https://portal.azure.com/#blade/HubsExtension/BrowseResourceBlade/resourceType/Microsoft.Search%2FsearchServices) and select the **Properties** tab in the middle of the Overview page. To check search service age, follow [these instructions](vector-search-index-size.md#how-to-check-service-creation-date). Regional support for extra capacity is noted in the footnotes of this article.|
25+
| [Availability zones](search-reliability.md#availability-zone-support) | Divides a region's data centers into distinct physical location groups, providing high-availability within the same geo. Regional support is noted in this article. |
26+
| [Azure AI enrichment](cognitive-search-concept-intro.md) | Refers to skills that make internal calls to Azure AI for enrichment and transformation during indexing. Integration requires that Azure AI Search coexists with an [Azure AI multi-service account](/azure/ai-services/multi-service-resource) in the same physical region. |
27+
| [Azure OpenAI integration](vector-search-integrated-vectorization.md) | Refers to skills and vectorizers that make internal calls to deployed embedding and chat models on Azure OpenAI. Check [Azure OpenAI model region availability](/azure/ai-services/openai/concepts/models#model-summary-table-and-region-availability) for the most current list of regions for each embedding and chat model. Specific Azure OpenAI models are in fewer regions, so be sure to check for joint regional availability before installing.|
28+
| [Azure AI Studio integration](vector-search-integrated-vectorization-ai-studio.md) | Refers to skills and vectorizers that make internal calls to the models hosted in the model catalog. Check [Azure AI Studio region availability](/azure/ai-studio/reference/region-support) for the most current list of regions. |
29+
| [Azure AI Vision 4.0 multimodal APIs for image vectorization](search-get-started-portal-image-search.md) | Refers to skills and vectorizers that call the multimodal embedding API. Check the [Azure AI Vision region list](/azure/ai-services/computer-vision/overview-image-analysis#region-availability) for joint regional availability. |
30+
| [Semantic ranking](semantic-search-overview.md) | Takes a dependency on Microsoft-hosted models in specific regions. Regional support is noted in this article. |
31+

<!-- Each cloud region noted in this article includes a column indicating support for the following features.

- [Availability zones](search-reliability.md#availability-zone-support) 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](/azure/ai-studio/reference/region-support) and [Azure OpenAI model region availability](/azure/reliability/availability-zones-service-support#azure-regions-with-availability-zone-support) 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](/azure/ai-services/computer-vision/overview-image-analysis#region-availability) and be sure to create both your Azure AI multi-service account and Azure AI Search service in one of those supported regions.
40+
Also, if you plan to use Azure AI Vision 4.0 multimodal APIs for image vectorization, it's available in a reduced list of regions. [Check the Azure AI Vision region list for multimodal embeddings](/azure/ai-services/computer-vision/overview-image-analysis#region-availability) and be sure to create both your Azure AI multi-service account and Azure AI Search service in one of those supported regions.
