Open AI model continuity plan for Standard Deployments in Australia East

Hi,

I am working with an Azure customer in Australia on Agentic AI solutions. We have provisioned standard deployments of GPT-4o in Aus East due to the customer's need for data sovereignty.

We have recently noticed in the customer's Azure AI Foundry that the standard deployment of GPT-4o in Aus East has a model retirement date of 3rd June 2026. This is the most advanced OpenAI model available for this deployment type.

What is Azure's plan for Open AI model availability for standard deployments in Aus East going forward? Will our customer have access to 4o or a replacement model?

Thanks
