@Veronica Ge We appreciate your patience on this. I had reached out to the product group team and got an update from them.
gpt-35-turbo-16kmodel is not included in the Azure AI studio model catalog at this time. See below:
There is no ETA at this moment on when this would be available. If you need it now, you should use
Azure OpenAI studio instead and deploy immediately.
Hope this helps.
