Hello Roger !
Thank you for posting on Microsoft Learn.
You're not alone, as I can see many organizations have reported long wait times when applying for access to models like GPT-4o with vision (GPT-Image-1) in Azure OpenAI.
As far as I know, Microsoft manually reviews GPT-Image-1 (multimodal) access requests, especially for enterprise accounts, due to responsible AI and compliance considerations.
There is no official SLA or auto-response timeframe, meaning your request might remain pending indefinitely unless explicitly approved or denied.
Try to raise a formal support ticket via Azure Portal under your subscription (choose Service and Subscription Management > Quota and Limits > Azure OpenAI).
I hope things will be sorted out quickly !
Good luck.
