Hi @kib kib , Thanks for using Microsoft Q&A Platform.
Yes, fine tuning available in specific regions only. I'm not sure of the region you are using and the model you are looking for. Could you please share these details?
Please refer to this page to know the model availability regions: https://learn.microsoft.com/en-us/azure/cognitive-services/openai/concepts/models#gpt-3-models-1
As there are some capacity issues in East US that can be a reason. Could you please try in other available regions and see if that helps.
Regards,
Vasavi
