   | [Azure AI services multiservice account](/azure/ai-services/multi-service-resource) | [Azure AI Vision multimodal](/azure/ai-services/computer-vision/how-to/image-retrieval) for image and text vectorization.

+If using the Azure OpenAI Service, it must have an associated [custom subdomain](/ai-services/cognitive-services-custom-subdomains). If the service was created through the Azure portal, this subdomain is automatically generated as part of your service setup. Ensure that your service includes a custom subdomain before using it with the Azure AI Search integration.

+Note that Azure OpenAI models created with an AI Studio service account are not supported. Only models from the Azure OpenAI Service are compatible with the Azure OpenAI integration.

 ### Public endpoint requirements
 
 All of the preceding resources must have public access enabled so that the portal nodes can access them. Otherwise, the wizard fails. After the wizard runs, you can enable firewalls and private endpoints on the integration components for security. For more information, see [Secure connections in the import wizards](search-import-data-portal.md#secure-connections).
