Hello Jeff
Thanks for reaching out to us. I can understand that South Central and West Europe should be the main region, product team is working on expanding the regions.
For example, text-davinci-003 is currently available in East US and West Europe. See this doc for the most up to date information on models and where they're available: Azure OpenAI models - Azure OpenAI | Microsoft Learn (although product team just added West Europe for text-davinci-003 and haven't gotten the doc updated quite yet).
If you need more information, please let me know which model you are interested in and I can check it for you.
I hope this helps.
Regards,
Yutong
