Azure OpenAI Responses API with computer-use-preview

Question

I am testing the Azure OpenAI Response endpoint. I got the basics working with rest calls - tool calling also works. In these calls I consume the models I have deployed in Azure Foundry.

I really want to test the CUA optiion, that is described here https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/responses?tabs=rest-api#computer-use - I am aware, that the documentation is for python, but the nuts and bolts should be the same underneath the python library.

When calling my endpoint like below, the response fails

$parameters = @{
	uri = "https://<mydeployment>.openai.azure.com/openai/responses?api-version=2025-03-01-preview"
	Method = "Post"
	Headers = @{
		"api-key" = "MySecretKey"
		}
	ContentType = "application/json"
	body = '{
		  "input": [
		    {
		      "role": "user",
		      "content": "Check the latest OpenAI news on bing.com\r\n"
		    }
		  ],
		  "reasoning": {
		    "summary": "concise"
		  },
		  "tools": [
		    {
		      "display_width": 1024,
		      "environment": "browser",
		      "display_height": 768,
		      "type": "computer_use_preview"
		    }
		  ],
		  "model": "computer-use-preview",
		  "truncation": "auto"
		}'
	}
Invoke-RestMethod @parameters

{
  "error": {
    "message": "The requested model \u0027-\u0027 with deployment name computer-use-preview does not exist.",
    "type": "invalid_request_error",
    "param": "model",
    "code": "model_not_found"
  }
}

It seems that the computer-use-preview model is not available. What do I need to do to deploy that model?

Hi @Axel B Andersen

Yes, registration is required, and you can complete it at link. Please ensure your registration is finalized and access is granted. Create a deployment: After registration, you must create a deployment for the computer-use-preview model in your Azure OpenAI resource.

Once your registration is approved and the deployment is correctly set up, you should be able to make API calls without encountering that error.

Hope this helps. Do let us know if you any further queries.
