Interaction between Azure Sponsorship Credits and Quota Tier upgrade to Tier 1

Quota Tier upgrades for Azure OpenAI / Foundry Models don't change, consume, or invalidate Azure Sponsorship credits.

Key points from the documented behavior:

1. Sponsorship credits vs. quota tiers are separate systems
   • Sponsorship credits are a billing/credits construct that discount eligible Azure consumption on the subscription or billing account.
   • Quota tiers in Foundry Models control rate limits and capacity for model usage and are driven by usage patterns and customer relationship (EA/MCA, payment history, etc.).
   • The quota tier change (for example, to Tier 1) doesn't alter how sponsorship credits are applied to eligible usage.
2. Sponsorship coverage still depends on what is being used
   • Azure Sponsorship credits apply only to eligible Azure services and, for Foundry Models, only to models sold directly by Azure.
   • Usage of models from partners/community (Anthropic, some Cohere, Hugging Face, some Meta, some Mistral AI, or other Marketplace/third‑party–billed models) is not covered by sponsorship credits, regardless of quota tier.
   • Quota Tier 1 simply allows more throughput; if that extra usage is on covered models, it will continue to draw down sponsorship credits; if it is on non‑covered models, it will be billed separately.
3. No special action is required to “preserve” credits
   • There is no documented requirement to change billing profiles, subscriptions, or sponsorship configuration when a Foundry Model quota tier is upgraded.
   • Sponsorship credits continue to apply automatically to eligible consumption until they are exhausted or the sponsorship term ends.
   • If using quota as a cost‑control mechanism, it is possible to opt out of automatic quota tier upgrades by setting the NoAutoUpgrade flag, but this is about rate limiting, not credit preservation.

In practice, to preserve sponsorship credits when moving to Tier 1:

• Ensure workloads primarily use models sold directly by Azure so usage is covered by the sponsorship.
• Avoid or closely monitor usage of partner/community models and other non‑covered services, as these will bypass sponsorship credits and generate separate charges.
