Current Limitation

Ballerina Azure OpenAI Model provider does not support GPT-5 series

Suggested Improvement

The GPT-5 series in Azure OpenAI support different API parameters compares to the GPT-4 series.

We need to fix our APIS to support that

Since these changes introduce breaking modifications that may require a redesign, and as this feature is not immediately needed (as discussed offline with @SasinduDilshara), we will deprioritize this issue.

We are currently migrating the models used by Choreo AI components to the GPT-5 series, as some of the existing models used by these components are being deprecated.
Progress is currently blocked due to the lack of GPT-5 series support in the Ballerina Azure OpenAI model provider.
Can we get an ETA for this?
