FLUX.2 Flex unavailable in Azure AI Foundry: SpecialFeatureOrQuotaIdRequired

Rudraksh bhandari 0

We are trying to use FLUX.2 Flex through Azure AI Foundry on an active Microsoft for Startups Sponsored subscription. The model is absent from the Foundry catalog for the subscription, and deployment returns SpecialFeatureOrQuotaIdRequired.

We have confirmed the documented prerequisites:

active Azure subscription with a valid payment method;
access to Microsoft Foundry and a Foundry project;
appropriate resource permissions, including Cognitive Services Contributor.

This is a model-entitlement/limited-access issue, not a GPU VM quota or regional-capacity request. The service is documented as available through global standard deployment, but it is not selectable for this subscription.

What exact entitlement, feature flag, quota, registration, or approval path is required to enable FLUX.2 Flex? If the model is not currently available to Microsoft for Startups Sponsored subscriptions, please confirm that and identify the supported credit-eligible alternative.

Related Microsoft requests: Startups advisory 2607260040000361 and support request 2607310010000447.

Hi @Rudraksh bhandari

SpecialFeatureOrQuotaIdRequired typically indicates that the deployment is blocked by an entitlement or subscription restriction rather than a regional capacity issue or missing RBAC permissions.

A few things to verify:

Subscription offer type. Since you're using a Microsoft for Startups Sponsored subscription, some AI Foundry models or deployment scenarios may not be available depending on the subscription offer and billing model.
Model availability. Although the FLUX documentation states that FLUX.2 Flex supports global standard deployment, availability can still depend on whether the model is enabled for your subscription.
Billing eligibility. Microsoft's guidance for Microsoft for Startups notes that sponsorship credits apply only to models that are sold and billed directly by Azure. It also recommends using the "Direct from Azure" collection in AI Foundry to identify eligible models.

Given that the model is absent from the catalog and the deployment fails with SpecialFeatureOrQuotaIdRequired, this appears to be an entitlement issue rather than a quota increase request. I would recommend asking Microsoft to confirm:

Whether FLUX.2 Flex is currently supported for the Microsoft for Startups Sponsored subscription offer.
Whether the subscription requires an internal feature flag or model entitlement.
Whether there's a documented registration or approval process to enable the model for that subscription type.

Since you've already provided the advisory and support case numbers, Microsoft should be able to verify the backend entitlement assigned to your subscription. This would help determine whether the behavior is expected or whether there's a provisioning issue.
