How to get access to model gpt-4o-realtime-preview?

Question

I am trying to deploy openai for this sample: https://github.com/Azure-Samples/aisearch-openai-rag-audio?tab=readme-ov-file

However the deployment ends with openai resource status "BadRequest".

The error:

{"code":"InvalidTemplateDeployment","message":"The template deployment 'openai' is not valid according to the validation procedure. The tracking id is 'fbaf8d2a-a064-442c-8f17-ed06a31765d2'. See inner errors for details.","details":[{"code":"SpecialFeatureOrQuotaIdRequired","message":"The current subscription does not have access to this model 'Publisher: , Format: OpenAI, Name: gpt-4o-realtime-preview, Version: 2024-10-01, Source: , SourceAccount: '."}]}

I am trying to deploy to eastus2.

Is it possible to get access to this model? How?

Thank you.
