Hi Andrew Curry
General Models (GPT 3.5, 4o, 4o-mini etc.) and Azure OpenAI access itself is not gated through forms.
To create an Azure OpenAI resource, we just need to search Azure OpenAI in search bar in portal.azure.com and create respective resource.
If you have a Free Trial or Pay as you go or Sponsored subscription, you can create Azure OpenAI resource already

You might need to assign concerned user as Cognitive Services OpenAI contributor to enable creation/inference of deployment

Please share any error trace or screen shot or model in concern to understand the issue better
Thank you
