Philippe REGALL Greetings & Welcome to Microsoft Q&A forum!
I have been onboarded on gpt-4 but in Azure OpenAI Studio I have no access to gpt-4 model in the list of models. What can I do ?
Just wanted to confirm if you have applied for access to GPT-4 and got it approved earlier?
If yes, you could have received regions as well with the access where you can deploy the resource.
Note that, due to high demand South Central US is temporarily unavailable for creating new resources and deployments.
Also, Could you try deploying via CLI as a workaround and let me know if that works?
See Create a resource and deploy a model using Azure OpenAI for more details.
Let me know if that helps.
