Jatin Kashyap Greetings & Welcome to Microsoft Q&A! Thanks for posting the question.
Which model you are trying to use for the deployment and in which region?
Please note that the deployment process may take some time to complete, depending on the size of your app and the resources you have allocated.
Please be patient and wait for the deployment to complete
Could you check if there are any errors or warnings in the deployment logs.
See Monitoring Azure OpenAI Service for more details on how to collect logs.
Do let me know if that helps or have any further queries.
