GPT 4.1 deployment shows Quota Unavailable in Azure AI foundry

I created an Azure Foundry Project with Japan East region and it is listed as a supported region for gpt 4.1 deployment. However when I try to deploy I am getting quota unavailable error and when I try to request Quota, the page is not getting loaded.

    For gpt-4.1 in Azure AI Foundry, quota is enforced per subscription, per region, and per model. “Quota unavailable” during deployment means that, for the selected subscription and region, there is no remaining Tokens‑per‑Minute (TPM) / Requests‑per‑Minute (RPM) capacity for that model, so the portal cannot create a deployment.

    Because the Quota page is not loading, use the documented troubleshooting patterns and then escalate if needed:

    1. Verify permissions and subscription
      • Ensure the account has at least Cognitive Services Usages Reader on the subscription to view quota and Owner or Contributor to request changes. If these roles are missing, the Quota experience can appear empty or non‑functional.
      • Confirm that the correct subscription is selected in the Foundry portal when checking quota.
    2. Check quota status and regional capacity
      • In Azure AI Foundry → Management Center → Quota, review the quota for gpt‑4.1 in Japan East once the page loads. Quota for Azure OpenAI is per region and per model; even if the model is supported in the region, the regional pool can be exhausted.
      • If the portal indicates capacity or quota exhaustion, this is expected behavior: the regional pool for gpt‑4.1 is currently full for that subscription.
    3. If the Quota page stays empty or “Request quota” is disabled
      • This matches the documented issue where the Quota page is empty or buttons are disabled. The guidance is:
        • Confirm the required roles as above.
        • If quota changes or page state do not update after waiting and refreshing, open an Azure support ticket so support can investigate the backend quota/capacity state for the subscription and region.
    4. Request more quota or reallocate
      • When the Request quota button becomes available, submit the quota increase request form for gpt‑4.1 in Japan East.
      • Alternatively, reduce TPM assigned to other deployments of the same model and region (if any) to free capacity, then retry the deployment.
    5. Short‑term workaround
      • If deployment is blocked in Japan East due to exhausted regional capacity or stuck allocation, deploy gpt‑4.1 in another supported region where quota is available, and use that deployment until quota in Japan East is increased or released.

    If quota appears consumed even though there are no active deployments, or the issue persists beyond normal propagation time, this can indicate retained or orphaned allocation; in that case, Azure support must correct the backend state for the subscription.
