Azure OpenAI: gpt-6.1-sol cannot be deployed – new subscription on Free Tier with 0 quota, quota requests declined

Problem description

I need to deploy gpt-6.1-sol (version 2026-09-29, Global Standard) in a newly created Azure subscription to migrate an existing production workload from another subscription in the same organization. Deployment fails with "Insufficient quota" for both Global Standard and Data Zone Standard.

Environment

  • Microsoft Foundry resource with Azure OpenAI, region: swedencentral
  • Subscription type: Azure Sponsorship
  • Quota tier API (Microsoft.CognitiveServices/quotaTiers/default) returns:
    • currentTierName: Free Tier
    • tierUpgradePolicy: OnceUpgradeIsAvailable
    • Tier assigned 2 days ago

What I've already tried

  • Foundry → Quota (Show all): 0/0 TPM for gpt-6.1-sol, gpt-5.1, and gpt-chat-latest across Global Standard and Data Zone Standard (APAC, US, EUR).
  • Submitted quota requests via the quota request form for Global Standard and multiple regions/data zones (APAC, EMEA, US). All were declined with: "The region you requested a quota increase in is not available to expand capacity at this time."
  • Smaller models available at the current tier (e.g., gpt-5-mini) deploy and work fine, which suggests the tier is what blocks gpt-6.1-sol.
  • Opened an Azure support case, which is still in progress.

Questions

  1. Is there a way to request a manual quota tier review or upgrade for a new subscription, instead of waiting for an automatic upgrade based on usage history?
  2. Can existing production usage in another subscription under the same organization be considered for the tier assignment?
  3. Is a "region capacity" decline message expected when the actual blocker is the Free Tier?

Any guidance from the community or Microsoft engineers would be appreciated.

    Hi Ariwibawa! You read it right: the blocker is the tier, not regional capacity. The quotas doc says subscriptions in the Free tier (Tier 0) aren't eligible for quota increases. Tier 0 only lists gpt-4.1-mini, gpt-5-mini, o4-mini and text-embedding-3-small on Global Standard. gpt-6.1-sol only shows up from Tier 1 (250K TPM Global Standard, 100K TPM Data Zone Standard). So 0/0 is expected, and quota requests won't help while you're on Free Tier.

    Your questions:

    1. Manual tier review: I couldn't find a documented way to request a tier upgrade. Upgrades are automatic and based on consumption across Foundry Models over time, your relationship with Microsoft (EA and MCA-E get higher tiers) and payment history. Eligibility can also depend on the subscription's Azure offer, and yours is Azure Sponsorship. Keep tierUpgradePolicy on OnceUpgradeIsAvailable as you have it. For a manual review your support case is the only channel. I'd say clearly in the case that the tier is "Free Tier" and the offer is Azure Sponsorship.
    2. Usage from your other subscription: the docs say tier eligibility is evaluated per subscription. Nothing says usage in another subscription of the same organization counts, so I wouldn't count on it.
    3. The "region capacity" message: the decline wording isn't documented. The documented rule is that Tier 0 isn't eligible for increases, so I'd treat that text as a generic decline.

    While you wait, I'd keep the gpt-6.1-sol traffic on the old subscription, since it already has the tier and quota, and move the rest of the workload first. If your organization has an EA or MCA-E, ask in the case whether a subscription under that agreement would get a higher tier. The docs say enterprise relationships are taken into account, but I can't confirm how that applies to a Sponsorship subscription.

    Update: Resolved. The subscription was automatically upgraded from Free Tier to Tier 1 after real usage.

    Sharing what worked in my case, in case it helps others. Please note this is only my experience. The upgrade criteria aren't published, so the result and timing may be different for your subscription.

    What happened

    • The new subscription started on Free Tier with 0/0 TPM for gpt-6.1-sol, and quota increase requests were declined with a "region capacity" message.
    • Azure Support confirmed that support can't change quota tiers manually. They advised generating usage with a model available on the current tier first, then requesting quota through the quota team ([email protected]).

    What I did

    1. Deployed gpt-5-mini (Global Standard), which was available on Free Tier.
    2. Used it for real workload tasks (document summarization and extraction with large inputs). That came to about 168 requests and 10M tokens in a short period, roughly 60K tokens per request.
    3. A few hours later, the quota tier API showed the subscription had moved to Tier 1, with no manual request.
    4. After that, gpt-6.1-sol (Global Standard) deployed successfully.

    How to check your tier

    az rest --method get --uri "https://management.azure.com/subscriptions/<subscription-id>/providers/Microsoft.CognitiveServices/quotaTiers/default?api-version=2025-10-01-preview"

    Check currentTierName, and make sure tierUpgradePolicy is OnceUpgradeIsAvailable. If it's NoAutoUpgrade, the subscription won't upgrade automatically.

    Takeaways (from my case only)

    • The "region capacity" decline message may appear even when the real blocker is the subscription's quota tier.
    • Real, sustained usage of a model allowed on your current tier seems to be what triggers the upgrade. In my case it happened within hours. Others have reported it taking weeks, so it likely depends on usage volume, payment history, and the subscription type.
    • Quota and tiers don't carry over from another subscription, even within the same organization.

    Hope this helps anyone stuck on Free Tier.
