Tier 1 upgrade pending, GPT-6 quota still 0/0 – how to get it applied

Question

Tier 1 upgrade pending, GPT-6 quota still 0/0 – how to get it applied

Volodymyr Shcherbyna 0

Hello,

On Oct 4 I got the "Eligibility for Quota Tier upgrade" email for my subscription (Free Tier → Tier 1). I did not opt out — I want the upgrade.

Right now gpt-5-mini and gpt-4.1-mini work, but gpt-6-astra, gpt-6-sol and gpt-6-luna are still at 0/0 TPM (Global Standard). Any call returns "Insufficient quota available for instant inference."

I also tried the quota request form for gpt-6-astra and gpt-6-luna — both were declined with "region not available to expand capacity". On Oct 5 I opened a support ticket (Service and subscription limits → Cognitive Services), no reply yet.

This is blocking a production rollout, so a few questions:

Can the Tier 1 upgrade be applied sooner?
Is there a way to see when it will take effect?
After the upgrade, will GPT-6 quota show up automatically, or do I need to submit a new quota request?

Happy to share the subscription ID privately.

Thanks!

There is no documented self-service way to force a quota tier upgrade sooner. Quota tiers increase automatically based primarily on consumption trends over time, and Microsoft also considers the customer’s relationship with Microsoft and payment history. Since a support ticket is already open, that is the correct escalation path for anything time-sensitive.
There is a documented way to check the current quota tier, but no documented ETA or pending-status view. The current tier can be checked with the control plane API:

curl -X GET \
  "https://management.azure.com/subscriptions/00000000-0000-0000-0000-000000000000/providers/Microsoft.CognitiveServices/quotaTiers?api-version=2025-10-01-preview" \
  -H "Authorization: Bearer $(az account get-access-token --resource https://management.azure.com --query accessToken -o tsv)" \
  -H "Content-Type: application/json"

Quota can also be viewed in Azure AI Foundry portal under Management > Quota for the region, where the approved quota and allocated quota are shown.

A Tier 1 upgrade does not guarantee GPT-6 quota. The GPT-6 documentation states that some quota tiers require quota requests for the GPT-6 family to deploy these models, and Tier 5 and Tier 6 subscriptions have quota by default. That means GPT-6 quota is not documented as automatically appearing for Tier 1.

Given the current symptoms:

gpt-5-mini and gpt-4.1-mini working is consistent with quota existing for those models.
gpt-6-astra, gpt-6-sol, and gpt-6-luna showing 0/0 TPM means no quota is currently assigned for those model/deployment combinations.
A declined quota request with “region not available to expand capacity” indicates capacity is not available for expansion in that region at this time.

For the production rollout, the supported next steps are:

Check the current quota tier with the quota tier API.
In Azure AI Foundry portal, go to Management > Quota and confirm whether GPT-6 Global Standard remains 0/0 after the tier change.
If it remains 0/0, submit a new quota request after the tier change, because approved increases keep the current tier but add more quota.
Keep the existing support ticket active for the urgent production blocker, because there is no documented self-service method to accelerate the tier change or override regional capacity limits.
