How to deploy an OpenAI model with Data Zone Standard in UK South

Nadia Prodanova 20

When attempting to deploy an OpenAI model using Data Zone Standard, the UK South region shows a quota of 0 of 50k TPM (as shown in Managment Center -> Quota). However, when trying to fill out the Azure AI Foundry Service: Request for Quota Increase form the region UK South seems unavailable for any of the GPT models. Is Data Zone Standard availability for GPT models in UK South subscription-based? Something that can be requested via support? Or a region limitation that will be enabled anytime soon?

Any guidance on expected availability or the correct process to request access would be appreciated.

Thanks!

Thanks for your response, I understand it's likely not available at the moment. Do you have any insight if the OpenAI models will be available in the UK region with Data Zone Standard? Thanks.

Hi Nadia Prodanova,
No. As of now, Azure OpenAI Data Zone Standard is not available in UK regions (UK South / UK West). Microsoft has not published support for UK regions yet, so Azure OpenAI models with Data Zone Standard cannot be deployed there.

Hi Nadia Prodanova,

This scenario is expected with Azure OpenAI deployments using Data Zone (standalone). Data zone isolated deployments have strict regional and networking constraints compared to standard Azure OpenAI resources.

Key points to check:

Model availability: Not all Azure OpenAI models currently support Data Zone (standalone) deployment. The deployment will fail if the selected model isn’t enabled for data‑zone isolation in that region.
Region alignment: The Azure OpenAI resource region, data zone, and any dependent resources (storage, search, networking) must be fully compatible and supported together.
Networking requirements: Data Zone (standalone) often requires private networking configurations. Public endpoint assumptions that work for non–data‑zone deployments may fail.
Portal vs ARM/CLI: The Portal may surface generic errors. Reviewing the Activity Log usually reveals the exact validation failure (model not supported, region mismatch, or networking constraint).
Documentation gap: Current docs explicitly list supported models and regions for Data Zone scenarios deployments outside those constraints aren’t supported yet.

In short: Data Zone (standalone) isn’t a drop‑in replacement for standard Azure OpenAI deployment model and region support must be explicitly validated first.

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

Thankyou!
