@EVA AI Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I see that you are looking for information on how to apply for access to the GPT-4 model for deployment on Azure OpenAI services.
A separate application for Azure OpenAI GPT-4 is no longer needed.
Please make sure you have applied to the Azure OpenAI Service. Once approved for the Azure OpenAI Service, you will have access to GPT-4 in a few selective regions only. See below screenshot.
GPT-4 and GPT-4-32k are now available to all Azure OpenAI Service customers. Availability varies by region. If you don't see GPT-4 in your region, please check back later. As mentioned in our below docs for East US- Due to high demand, availability is limited in the region.
More Info here.
If you have any follow-up questions, please let me know. I would be happy to answer.
