Fine-tuning Availability for OpenAI Models in Azure

Is it currently possible to fine-tune OpenAI models like GPT-4, GPT-4o, and GPT-4o-mini? I have been attempting to fine-tune these models over the past few days in the North Central US and Sweden Central regions, which are listed as available for fine-tuning here: Supported Models for Fine-tuning.

However, I consistently encounter the following error when uploading the training data:

I have attempted the role assignment mentioned in the error message without success, and the file format is correct, as I can successfully upload it for fine-tuning other models, such as Phi-3-mini-4k-instruct. Additionally, I tried using Machine Learning Studio, but the GPT models also appear to be unavailable for fine-tuning in both regions.

What are the next steps to resolve this issue, or are the OpenAI models temporarily unavailable for fine-tuning?

    Hello Alison Felix,

    Greetings and Welcome to Microsoft Q&A!

    I understand that you're encountering issues with fine-tuning OpenAI models like GPT-4, GPT-4o, and GPT-4o-mini in the North Central US and Sweden Central regions. Please consider these steps:

    Ensure that your role assignment, data quality, and API/SDK versions are correctly configured. Verify that your account has the necessary permissions, such as the Cognitive Services OpenAI Contributor or Owner role, assigned at the appropriate scope (subscription, resource group, or specific resource).

    Confirm that your training dataset meets the required JSONL format, is properly structured, and does not contain malformed entries, as data quality issues can cause upload failures.

    Check that you are using the latest version of the Azure OpenAI API and SDK, as outdated versions may lack support for fine-tuning or contain unresolved bugs.

    If the issue persists, consider testing in another supported region.Kindly refer this Troubleshooting for Azure OpenAI fine-tuning.

    I hope you understand. And, if you have any further query do let us know.

    Thank you!
