Hi all; Is the new version 2 OpenAIClient and associated classes documented anywhere. All I can find is the 1.0 documentation . And hopefully guidance on how to change my code for the new API. Changes I’ve found (likely many more): Namespace changed from Azure.AI.OpenAI to OpenAI Parameters for OpenAIClient constructor have changed (not sure to what - no documentation). The following classes no longer exist. ChatRequestMessage ChatRequestSystemMessage ChatRequestUserMessage ChatCompletionsOptions The method OpenAIClient.GetChatCompletionsAsync() no longer exists. thanks - dave

We close this issue with support ticket, once there is a solution from support team, will post here. Thanks, Yutong -Please kindly accept the answer if you feel helpful to support the community, thanks a lot.

Hi all;

Is the new version 2 OpenAIClient and associated classes documented anywhere. All I can find is the 1.0 documentation.

And hopefully guidance on how to change my code for the new API.

Changes I’ve found (likely many more):

Namespace changed from Azure.AI.OpenAI to OpenAI
Parameters for OpenAIClient constructor have changed (not sure to what - no documentation).
The following classes no longer exist.
1. ChatRequestMessage
2. ChatRequestSystemMessage
3. ChatRequestUserMessage
4. ChatCompletionsOptions
The method OpenAIClient.GetChatCompletionsAsync() no longer exists.

thanks - dave

Hello Dave,

Thanks for reaching out to us, there is a dropdown menu and if you click on it you should see the 2.0 version as below -

I hope this helps.

@YutongTie-MSFT First off thanks. My wife says I'm am the least observant person in the world and yet again - I missed something obvious.

Second, when I upgraded in NuGet it changed the namespace to OpenAI for OpenAI.OpenAIClient and while the documentation shows

AzureOpenAIClient (Uri endpoint, System.ClientModel.ApiKeyCredential credential, Azure.AI.OpenAI.AzureOpenAIClientOptions options = null);

It does not exist (compile error). Also, is there documentation saying how I should now do the following as all these classes are now gone?

				var messages = new List<ChatRequestMessage>()
				{
					new ChatRequestSystemMessage(_systemMessage),
					new ChatRequestUserMessage(text),
				};

				var options = new ChatCompletionsOptions("sandbox1", messages)
				{
					MaxTokens = 1500,
					Temperature = 0,
					FrequencyPenalty = 0,
					PresencePenalty = 0,
				};

				var chatCompletions = await Client.GetChatCompletionsAsync(options);

thanks - dave

Hello Dave,

Thanks for your confirmation, below is a code sample you may want to refer to, please have a try -

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using Azure;
using Azure.Identity;
using Azure.AI.OpenAI;
using Azure.AI.OpenAI.Models;

public class ChatExample
{
    private static string _systemMessage = "Your system message here";
    private static AzureOpenAIClient Client;

    public static async Task Main(string[] args)
    {
        // Define the endpoint
        var endpoint = new Uri("https://my-resource.openai.azure.com");

        // Use DefaultAzureCredential for authentication
        TokenCredential credential = new DefaultAzureCredential();

        // Create options if needed (can be null if default options are sufficient)
        var options = new AzureOpenAIClientOptions();

        // Initialize the AzureOpenAIClient with TokenCredential
        Client = new AzureOpenAIClient(endpoint, credential, options);

        // Define user message
        string text = "Your user message here";

        // Create chat messages
        var messages = new List<ChatMessage>
        {
            new ChatMessage(ChatMessageRole.System, _systemMessage),
            new ChatMessage(ChatMessageRole.User, text)
        };

        // Set up chat completion options
        var chatOptions = new ChatCompletionsOptions
        {
            Messages = messages,
            MaxTokens = 1500,
            Temperature = 0,
            FrequencyPenalty = 0,
            PresencePenalty = 0
        };

        // Get chat completions
        var chatCompletions = await Client.GetChatCompletionsAsync(chatOptions);

        // Handle the response
        Console.WriteLine(chatCompletions.Choices[0].Message.Content);
    }
}

Regards,

@YutongTie-MSFT I tried this and found a couple of problems:

ChatMessage is an abstract class. So I can't create the new ChatMessage() calls.

The class ChatCompletionsOptions does not exist.

The method Client.GetChatCompletionsAsync() does not exist.
