Structured Outputs with Azure OpenAi

[fitprotracker]

Describe the bug
I am trying the small code snippet in the Wiki about structured outputs. I am using Provider Type Azure with the Betalgo.OpenAI (8.7.2) library. The test is running in a .NET console project using the latest model gpt-4.0 (model version 2024-08-06).

Your code piece

var sdk = new OpenAIService(settings: new OpenAiOptions()
{
    ProviderType = ProviderType.Azure,
    ApiKey = "",
    DeploymentId = "xxx-4o-new",
    ResourceName = "xxx-ai-dev-2"
});

var completionResult = await sdk.ChatCompletion.CreateCompletion(new()
{
    Messages = new List<ChatMessage>
    {
        ChatMessage.FromSystem("You are a helpful math tutor. Guide the user through the solution step by step."),
        ChatMessage.FromUser("How can I solve 8x + 7 = -23?")
    },
    Model = "gpt-4o-2024-08-06",
    ResponseFormat = responseFormat
});


BadRequest: response_format value as json_schema is enabled only for api versions 2024-08-01-preview and later

Can you try with setting api version to preview?

var sdk = new OpenAIService(settings: new OpenAiOptions()
{
    ProviderType = ProviderType.Azure,
    ApiKey = "",
    DeploymentId = "xxx-4o-new",
    ResourceName = "xxx-ai-dev-2",
    ApiVersion = "2024-08-01-preview"
});
