Hi @Anonymous , Thanks for using Microsoft Q&A Platform.
Due to high demand, fine-tuning is no longer available for customers in West Europe region. And it is also noted in our documentation here: https://learn.microsoft.com/en-us/azure/cognitive-services/openai/concepts/models#model-summary-table-and-region-availability
East US and West Europe were previously available, but due to high demand they are currently unavailable for new customers to use for fine-tuning. Please use US South Central region for fine-tuning.
So, I would recommend you try with US South Central region for fine-tuning.
I hope this helps. Let me know if you need more clarification.
Regards,
Vasavi
