# Create an Azure AI Search service in the portal

[**Azure AI Search**](search-what-is-azure-search.md) is a vector and full text information retrieval solution for the enterprise, and for traditional and generative AI scenarios.
20-
21-
If you have an Azure subscription, including a [trial subscription](https://azure.microsoft.com/pricing/free-trial/?WT.mc_id=A261C142F), you can create a search service for free. Free services have limitations, but you can complete all of the quickstarts and most tutorials, except for those featuring semantic ranking (it requires a billable service).
19+
[**Azure AI Search**](search-what-is-azure-search.md) is a comprehensive information retrieval platform for the enterprise. It supports traditional search and conversational AI-driven search for "chat with your data" experiences over your proprietary content.
2220

2321
The easiest way to create a service is using the [Azure portal](https://portal.azure.com/), which is covered in this article. You can also use [Azure PowerShell](search-manage-powershell.md#create-or-delete-a-service), [Azure CLI](search-manage-azure-cli.md#create-or-delete-a-service), the [Management REST API](search-manage-rest.md#create-or-update-a-service), an [Azure Resource Manager service template](search-get-started-arm.md), a [Bicep file](search-get-started-bicep.md), or [Terraform](search-get-started-terraform.md).

+ [Tier](search-sku-tier.md) (Free, Basic, Standard, and so forth) determines the underlying physical hardware and billing. Some features are tier-constrained.
33-
+ [Service region](#choose-a-region) can determine the availability of certain scenarios and higher storage limits. If you need availability zones or [AI enrichment](cognitive-search-concept-intro.md) or more storage, create the resource in a region that provides the feature.
31+
+ [Region](search-region-support.md) determines data residency and the availability of certain features. Semantic ranking, Azure AI integration, and availability zones come with region requirements. Make sure your region of choice supports the features you need.
32+
33+
+ [Service tier](search-sku-tier.md) (Free, Basic, Standard, and so forth) determines infrastructure, service limits, and billing. Some features aren't available on lower or specialized tiers.

Free services have limitations, but you can complete all of the quickstarts and most tutorials, except for those featuring semantic ranking (it requires a billable service).

To try search for free, [open a free Azure account](https://azure.microsoft.com/pricing/free-trial/?WT.mc_id=A261C142F) and then create your search service by choosing the **Free** tier. You can have one free search service per Azure subscription. Free search services are intended for short-term evaluation of the product for nonproduction applications. If you want to move forward with a production application, create a new search service on a billable tier.

Alternatively, you can use free credits to try out paid Azure services. With this approach, you can create your search service at **Basic** or higher to get more capacity. Your credit card is never charged unless you explicitly change your settings and ask to be charged. Another approach is to [activate Azure credits in a Visual Studio subscription](https://azure.microsoft.com/pricing/member-offers/msdn-benefits-details/?WT.mc_id=A261C142F). A Visual Studio subscription gives you credits every month you can use for paid Azure services.

# Azure AI Search feature availability across clouds regions
17+
18+
This article identifies the cloud regions in which Azure AI Search is available. It also lists which premium features are available in each region:
19+
20+
- [Semantic ranking](semantic-search-overview.md) depends on models hosted by Microsoft. These models are available in specific regions.
21+
- [Azure AI integration](cognitive-search-concept-intro.md) (skills and vectorizers) requires that Azure AI Search coexist with an [Azure AI multi-service account](/azure/ai-services/multi-service-resource) in the same region. The following tables indicate whether Azure AI is generally available in the same region as Azure AI Search.
22+
23+
We recommend that you [check Azure AI Studio region availability](/azure/ai-studio/reference/region-support) for an updated list of regions for that feature.
24+
25+
Also, if you're using Azure AI Vision 4.0 multimodal APIs for image vectorization, it's available in a more limited set 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.
26+
27+
> [!NOTE]
28+
> 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](search-limits-quotas-capacity.md#service-limits)
