Gpt-4o-mini doesn't support structured outputs in Azure AI Studio deployments

Question

The gpt-4o-mini accessible through Open AI's endpoint supports structured outputs but through Azure it does not. The following error is seen when structured outputs are used using gpt-4o-mini from Azure:

openai.BadRequestError: Error code: 400 - {'error': {'message': "Invalid parameter: 'response_format' of type 'json_schema' is not supported with this model.

Hello @Adeeb Faiyaz

Thanks for reaching out to us, unfortunately GPT-4o-mini doesn't support structured output right now, currently only gpt-4o version: 2024-08-06 supports structured outputs.

This feature will come soon but there is currently no ETA for this feature based on product team's guidance.
