Request Standard (Regional) deployment for gpt-5.x in Australia East - healthcare workload

Hello @Joe

Thank you for reaching out and for providing the detailed background on your healthcare workload and compliance requirements.

From your description, I understand that your primary requirement is to deploy a pay-as-you-go Standard (Regional) model in Australia East, so that prompts and completions are processed within Australia East to satisfy your data residency and healthcare compliance requirements. I also understand that the currently available deployment options (Global Standard, Data Zone Standard, or Provisioned Throughput) do not meet your operational or compliance requirements.

Based on the current Microsoft documentation, please find our observations below.

1. Regional Standard vs. Global Standard vs. Data Zone Standard

According to Microsoft Learn, deployment types differ in how requests are processed:

Regional Standard processes prompts and responses only within the Azure region where the deployment is hosted. This is the deployment type intended for workloads requiring processing within a specific Azure region.

Global Standard routes requests through Microsoft's global routing infrastructure and may process requests in any Azure region where the model is available. Therefore, it does not guarantee processing exclusively within Australia East.

Data Zone Standard processes requests within the Microsoft-defined data zone associated with the resource's geography. While processing remains within the data zone, it is not equivalent to processing exclusively within a single Azure region such as Australia East.

If your compliance policy specifically requires inference to remain within Australia East, Regional Standard is the deployment type designed to meet that requirement.

2. GPT-5.x Regional Standard availability in Australia East

Microsoft publishes model availability by deployment type and region through the Azure AI Foundry model catalog.

Based on the currently published availability:

• GPT-5.x models such as GPT-5.1 and GPT-5.4-mini are currently available in several deployment types, including Global Standard and Data Zone Standard, depending on region.
• However, GPT-5.1 and GPT-5.4-mini are not currently listed as available for Standard (Regional) deployment in Australia East.

Model availability is dependent on the combination of:

• Azure region
• Deployment type
• Model lifecycle
• Capacity availability

Therefore, even if the Azure portal displays "Standard" as a deployment type, a particular model may not be deployable if it is not currently available for that specific region and deployment type.

Microsoft Learn does not publish release timelines or ETAs for future regional model availability.

3. Why GPT-4o Standard / GPT-4.1-mini Standard deployments are blocked

The ServiceModelDeprecating error indicates that the model has entered its deprecation lifecycle and is no longer accepting new deployments.

Microsoft documentation explains that:

• Models in the "No new customers" phase can only be deployed by subscriptions that already have an existing deployment of that model.
• Once a model reaches deprecation, customers are expected to migrate to the documented successor model.

At this time, Microsoft documentation does not describe any public allowlist or exception process that enables new Regional Standard deployments for deprecated models.

4. Recommended deployment path

For workloads requiring Australia-only inference, Microsoft documentation recommends using Regional Standard whenever an appropriate model is available.

If the required GPT-5.x model is not currently available as Regional Standard in Australia East, the available options are:

• Verify that the deployment type is Regional Standard rather than Global Standard or Data Zone Standard.
• Verify that the Azure AI Foundry resource itself is deployed in Australia East.
• Submit a quota request if the required deployment type (Regional Standard or Data Zone Standard) is not exposed for your subscription or region.
• If Regional Standard capacity is unavailable, monitor future model availability as Microsoft expands regional support.

If your compliance requirements permit processing within the Microsoft data zone rather than exclusively within Australia East, you may also evaluate Data Zone Standard, as current availability tables indicate that certain GPT-5.x models (including GPT-5.4-mini) are available under Data Zone Standard for Australia East. However, this deployment type does not guarantee processing exclusively within the Australia East Azure region.

5. Vision, PDF extraction, and JSON Schema requirements

Your workload requires:

• PDF/image input (vision)
• Structured JSON output
• Pay-as-you-go billing
• Regional processing within Australia East

While Microsoft documentation describes model capabilities and deployment options separately, it does not currently identify a GPT-5.x Regional Standard deployment in Australia East that satisfies all of these requirements simultaneously.

Accordingly, we cannot recommend a specific GPT-5.x Regional Standard deployment in Australia East based on the current published documentation.

6. Responses to your specific questions

1. When will GPT-5.1 or GPT-5.4-mini become available as Regional Standard in Australia East?

Microsoft has not published a roadmap or ETA for future Regional Standard availability of specific GPT-5.x models in Australia East.

2. Is there an allowlist or exception process for GPT-4o Standard or GPT-4.1-mini Standard?

Current Microsoft documentation does not describe any public allowlist or exception process for deploying deprecated Regional Standard models. Models in the "No new customers" phase remain available only to eligible subscriptions that already have existing deployments.

3. What is the recommended deployment for healthcare workloads requiring Australia-only inference?

Regional Standard is the recommended deployment type for single-region inference.

If Regional Standard is unavailable for the required model, Microsoft documentation does not currently identify an alternative pay-as-you-go deployment that guarantees Australia East-only inference while providing GPT-5.x capabilities.

If your compliance policy allows processing within the Microsoft data zone rather than a single Azure region, Data Zone Standard may be considered.

I Hope this helps. Do let me know if you have any further queries.

Thank you!

Thanks for the reply, I need Regional Standard for this application. How does one go about contacting support for further assistance - without an ETA or further support we will be unable to use azure.

+1 how do we raise a quota request? This is a huge bug bearer and foundry mires in comparison to what's available in bedrock
