Cannot Deploy GPT-3.5/GPT-4 Models in Azure OpenAI – Only Deprecated and Embedding Models Available

Hi everyone,

I’m working with Azure OpenAI and trying to build a Logic Apps workflow that requires text completion/chat (for example, GPT-3.5 Turbo or GPT-4). My Azure OpenAI resource (dev-autodailer-openai, resource group arkserv-dev-rg) only lists old, deprecated models such as text-davinci-003 and several embedding models. I have run the following CLI commands:

text
az cognitiveservices account list-models --name dev-autodailer-openai --resource-group arkserv-dev-rg

The only available models are either legacy/completion (which are deprecated and disabled) or embedder models (text-embedding-3-small, text-embedding-3-large). Attempts to deploy text-davinci-003 and similar fail with "ServiceModelDeprecated". Trying to deploy GPT-4/GPT-3.5-turbo results in "DeploymentModelNotSupported" or the model does not appear at all.

My questions:

  • How can I enable access to current completion/chat models (like GPT-3.5 Turbo, GPT-4, GPT-4o) for my Azure OpenAI resource?

Is there a process or special approval required for my subscription?

Are there regional or subscription limitations I should be aware of?

Has anyone successfully transitioned from deprecated legacy models to the newer/generally available chat/completion models, and how?

Relevant context:

Use case: Automating communications in Logic Apps, requires high-quality text completions.

Resource Name: dev-autodailer-openai

Resource Group: arkserv-dev-rg

I have read through the deprecation and update docs and model availability guidance.

Any insights or help with next steps would be appreciated! Thank you.Hi everyone,

    Hello Vaibhav !

    Thank you for posting on Microsoft Learn.

    Azure OpenAI requires explicit approval for most chat/completion models. You need to:

    1. Submit an Azure OpenAI access request form
    2. Provide details about your use case (which you have - automating communications)
    3. Wait for approval (typically 1-10 business days)

    GPT-3.5 Turbo and GPT-4 are available in most Azure regions, but you should check the Azure OpenAI service availability page and consider creating your resource in a major region like East US or West Europe if you don't see models

    Once approved, you can reate a new deployment for the desired model (gpt-35-turbo, gpt-4...) and update your Logic Apps workflow to use the new model endpoint.

    After approval, you should see available models with:

    
az cognitiveservices account list-models \

  --name dev-autodailer-openai \

  --resource-group arkserv-dev-rg \

  --query "[].{name:name, version:version, capabilities:capabilities}" \

  --output table

    If you need immediate access, you can use Azure AI Studio which sometimes provides quicker access to models and check if your subscription qualifies for pay-as-you-go access (no approval needed in some cases).
