GPT-5.6 quota entitlement missing after Tier 1 upgrade

Question

Subscription ID:
27643e74-ec81-43d4-8cfa-780ff36f99c6

The quota tier control-plane API confirms that this subscription is Tier 1.
However, all GPT-5.6 quota entries still have a limit of zero:

- OpenAI.GlobalStandard.gpt-5.6-luna: 0
- OpenAI.GlobalStandard.gpt-5.6-sol: 0
- OpenAI.GlobalStandard.gpt-5.6-terra: 0
- OpenAI.DataZoneStandard.gpt-5.6-luna: 0
- OpenAI.DataZoneStandard.gpt-5.6-sol: 0
- OpenAI.DataZoneStandard.gpt-5.6-terra: 0

According to the published Tier 1 quota reference, each GPT-5.6
GlobalStandard model should have 1,000,000 TPM and each
DataZoneStandard model should have 333,000 TPM.

Please synchronize or repair the GPT-5.6 model-level quota entitlements
for this subscription.

Hi CatFly,

When your subscription upgrades to Tier 1 in Azure OpenAI / AI Foundry, regional quota limits for newly released models (like GPT-5.6) do not automatically populate if the target Azure region is currently at capacity or if model deployment defaults haven't been assigned to the subscription.

Here is how to resolve it:

1. Check Regional Availability: Open Azure AI Foundry / Azure Portal and test creating a deployment in a different supported region (e.g. East US 2 or Sweden Central), as model quota allocations are region-specific.
2. Request Quota Increase via Portal: Go to Azure Portal > Azure OpenAI > Quotas > Select gpt-5.6 > Click Request Increase. Tier 1 subscriptions receive priority auto-approval for quota requests.
3. Refresh Quota Control-Plane: If it remains at 0 after 24 hours, submit a free Billing & Quota Support Request under Issue Type: Quota to refresh your subscription's Tier 1 model entitlement tables.
