A catalog of AI models in Microsoft Foundry that you can discover, compare, and deploy using Azure’s built‑in tools for evaluation, fine‑tuning, and inference
Hello Hien Duong,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you stated that "Region not available for model deployments in Azure AI Foundry."
Your Azure AI Foundry project is not the main problem, because GPT‑4.1 is available in Foundry, but your new Pay‑as‑you‑go subscription currently has no deployable GPT‑4.1 quota/entitlement for the selected deployment type in any eligible region. Because quota is scoped by subscription, model, region, and deployment type, Foundry correctly hides all regions when none have usable quota. - https://learn.microsoft.com/en-us/azure/foundry/openai/quotas-limits, https://learn.microsoft.com/en-us/azure/foundry/how-to/quota
The best fix is to go to Foundry > Operate > Quota, check GPT‑4.1 2025-04-14 for the intended deployment type, and request quota for a supported region/deployment type combination. Use Global Standard first unless you have strict data-residency requirements. After quota is approved and visible, the region list will become selectable and deployment will succeed. - https://learn.microsoft.com/en-us/azure/foundry/how-to/quota, https://learn.microsoft.com/en-us/azure/foundry/foundry-models/concepts/deployment-types, and https://learn.microsoft.com/en-us/azure/foundry/foundry-models/concepts/models-sold-directly-by-azure-region-availability gives more insights and steps to fix it.
I hope this is helpful! Do not hesitate to let me know if you have any other questions, steps or clarifications.
