Hello @Ryuto Endo , Thanks for using Microsoft Q&A Platform.
Firstly, you can certainly use multiple models in the same workspace.
You can create separate resources for each model, or you can create multiple models in the same resource region if available. The recommended approach would depend on your specific use case and requirements.
Please refer to the model page for the availability regions and the token limits: https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/models
For pricing information, please visit here: https://azure.microsoft.com/en-us/pricing/details/cognitive-services/openai-service/
I hope this helps.

Vasavi
