An Azure service that provides access to OpenAI’s GPT-3 models with enterprise capabilities.
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
- Deployed gpt-5-mini (Global Standard), which was available on Free Tier.
- 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.
- A few hours later, the quota tier API showed the subscription had moved to Tier 1, with no manual request.
- 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.
