Unable to see o3 pro deployment in Sweden central

Question

Unable to see o3 pro deployment in Sweden central

Kamil Cisewski 40

I created deployment of o3 pro in Sweden Central.

I try to use it in Chat Playground - Azure Ai Foundry but it was not on the list for chat.

This deployment existed in the list of deployments, but I'm unable to see this deployment on the chat in the Foundry.

Does anyone had similar issue?

Hello,

Welcome to Microsoft Q&A,

Chat Completions API is not enabled for o3-pro, this is why you can't use it in Chat Playground or Azure AI Foundry chat interface.

This happens because:

Microsoft may allow deployment of certain models like o3-pro for API use only initially.

UI integrations (like Playground or AI Foundry) may lag behind in support for preview or limited-access models, especially newer ones like o3-pro. User's image

What You Can Do Instead

You can still interact with o3-pro through:

Azure OpenAI Responses API

Function/tool calls

Structured output handling

Streaming responses

Image input and reasoning

But all this must be done via code or API clients, not in the GUI tools (like Chat Playground or Foundry Chat tab).

Hi Yalagri Manjunath, Bharath Reddy,

Please find the sample codes below,

using Azure;
using Azure.AI.OpenAI;

string endpoint = "https://<your-resource-name>.openai.azure.com/";
string apiKey   = "<your Azure OpenAI API key>";
string deploymentName = "o3-pro";  // Your deployment name for the o3-pro model

// 1. Configure the AzureOpenAIClient to use the preview API version (supports o3-pro)
var options = new AzureOpenAIClientOptions(
    AzureOpenAIClientOptions.ServiceVersion.V2025_04_01_Preview
);
AzureOpenAIClient client = new(new Uri(endpoint), new AzureKeyCredential(apiKey), options);

// 2. Get a Response client for the o3-pro deployment and send a prompt
OpenAIResponseClient responseClient = client.GetOpenAIResponseClient(deploymentName);
Response<AIResponse> response = responseClient.CreateResponse(
    "Hello, o3-pro! How do I use the Responses API in Azure OpenAI?"
);

// 3. Extract and output the assistant's answer from the response
AIResponse result = response.Value;
foreach (var item in result.OutputItems)
{
    if (item is MessageResponseItem message)  // This contains the model's answer
    {
        foreach (var contentPart in message.Content)
        {
            Console.WriteLine(contentPart.Text);  // Print each text segment of the answer
        }
    }
}
