Hello @Anonymous
Thanks for your patience, unfortunately, I just got confirmation from product team -
Cognitive Services is not listed on the list of Azure Services with Availability Zone Support, so Azure OpenAI Service as part of Cognitive Services is not in list: Azure services that support availability zones | Microsoft Learn
I am sorry for all inconveniences, thanks for your understanding.
Regards,
Yutong
