Jay Robinson Greetings & Welcome to Microsoft Q&A forum!
I can't create a custom model in either Japan East or US East region. What region currently supports creating custom models? None of the models show available fine-tuning regions on the following page:
Yes, Fine tuning is currently not available for new customers as it is turned off for all regions. Unfortunately, we don't have any ETA at this moment when fine tuning opens again.
The models page will be updated as soon as we open up regions for fine tuning and users should be able to submit requests when it is made available.
If you have previously fine-tuned & deployed in a region, then you can fine tune in that region if it's available.
Alternatively, you could use Azure OpenAI on your data feature with Open AI which might remove the need / requirement for fine tuning.
Hope this helps. Do let us know if you have any further queries.
