Hi Robert,
As far as I can see these models fall under legacy and not supported:
Azure OpenAI Service offers a variety of models for different use cases. The following models are not available for new deployments beginning July 6, 2023. Deployments created prior to July 6, 2023 remain available to customers until July 5, 2024. We recommend customers migrate to the replacement models prior to the July 5, 2024 retirement.

I understand that you an employee, so you may need to reference internal resourcing to see if you can deploy these models.
If this is helpful please accept answer.
