tsuzuki-s Greetings & Welcome to Microsoft Q&A forum!
Will this full quota reset after a certain period of time, or once it is full, do I have to add more quota to continue using it?
If you have reached the quota limit for a specific region, you can continue using the service by deploying your resources to another region. However, the quota limit for a specific region will not reset after a certain period of time. If you need to increase the quota limit for a specific region, you can apply for a quota increase.
Quota increase requests can be submitted from the Quotas page of Azure OpenAI Studio. Please note that due to overwhelming demand, quota increase requests are being accepted and will be filled in the order they are received. Priority will be given to customers who generate traffic that consumes the existing quota allocation, and your request may be denied if this condition isn't met.
For other rate limits, please submit a service request.
For your scenario, I suggest explore Azure OpenAI Dynamic quota. Dynamic quota is an Azure OpenAI feature that enables a standard (pay-as-you-go) deployment to opportunistically take advantage of more quota when extra capacity is available.
I hope this helps. Do let me know if you have any further queries.
