Sample Usage

The repository contains a sample project named OpenAI.Playground to help you understand how the library works. However, please exercise caution while experimenting, as some test methods may result in unintended consequences such as file deletion or fine-tuning.

!! It is highly recommended that you use a separate account instead of your primary account while using the playground. Some test methods may add or delete your files and models, potentially causing unwanted issues. !!

Your API Key can be obtained from here: https://platform.openai.com/account/api-keys
Your Organization ID can be found here: https://platform.openai.com/account/org-settings

Without Using Dependency Injection

var openAIService = new OpenAIService(new OpenAIOptions()
{
    ApiKey = Environment.GetEnvironmentVariable("MY_OPEN_AI_API_KEY")
});

Using Dependency Injection

secrets.json

"OpenAIServiceOptions": {
    "ApiKey": "Your api key goes here",
    "Organization": "Your Organization Id goes here (optional)",
    "UseBeta": "true/false (optional)"
}

(To use user secrets: Right-click your project name in "Solution Explorer", then click "Manage User Secrets". This is a good way to keep your API keys secure.)

Program.cs

serviceCollection.AddOpenAIService();

OR

serviceCollection.AddOpenAIService(settings => { settings.ApiKey = Environment.GetEnvironmentVariable("MY_OPEN_AI_API_KEY"); });

After injecting your service, you can retrieve it from the service provider:

var openAiService = serviceProvider.GetRequiredService<IOpenAIService>();

You can set a default model (optional):

openAiService.SetDefaultModelId(Models.Gpt_4o);

Chat GPT Sample

var completionResult = await openAiService.ChatCompletion.CreateCompletion(new ChatCompletionCreateRequest
{
    Messages = new List<ChatMessage>
    {
        ChatMessage.FromSystem("You are a helpful assistant."),
        ChatMessage.FromUser("Who won the world series in 2020?"),
        ChatMessage.FromAssistant("The Los Angeles Dodgers won the World Series in 2020."),
        ChatMessage.FromUser("Where was it played?")
    },
    Model = Models.Gpt_4o,
});
if (completionResult.Successful)
{
    Console.WriteLine(completionResult.Choices.First().Message.Content);
}

Notes

Due to time constraints, not all methods have been thoroughly tested or fully documented. If you encounter any issues, please report them or submit a pull request. Your contributions are always appreciated.

Needless to say, I cannot accept responsibility for any damage caused by using the library.

Changelog

9.0.0

• .NET 9 support added.
• ⚠️ Support for .NET 6 and .NET 7 has ended.
• Fixed utility library issues and synced with latest version.

8.10.1

• Fixed an issue with the Store parameter being included in requests by default, causing errors with Azure OpenAI models. The parameter is now optional and excluded from serialization unless explicitly set.

8.10.0

• Added support for Microsoft.Extensions.AI IChatClient and IEmbeddingGenerator (more information will be coming soon to the Wiki).

• Added missing Temperature and TopP parameters to AssistantResponse.

• Added missing Store parameter to ChatCompletionCreateRequest.

• Breaking Changes:

  • ⚠️ CreatedAt parameter renamed to CreatedAtUnix and converted to long instead of int. Added CreatedAt parameter as DateTimeOffset type, which will automatically convert Unix time to DateTime.

8.9.0

• Realtime API implementation is completed. As usual this is the first version and it may contain bugs. Please report any issues you encounter.
• Realtime Sample

8.8.0

• Compatibility Enhancement: You can now use this library alongside the official OpenAI library and/or Semantic Kernel within the same project. The name changes in this update support this feature.

• Namespace and Package ID Update: The namespace and PackageId have been changed from Betalgo.OpenAI to Betalgo.Ranul.OpenAI.

• OpenAI Naming Consistency: We've standardized the use of "OpenAI" throughout the library, replacing any instances of "OpenAi" or other variations.

• Migration Instructions: Intellisense should assist you in updating your code. If it doesn't, please make the following changes manually:

  • Switch to the new NuGet package: Betalgo.Ranul.OpenAI instead of Betalgo.OpenAI.
  • Update all namespaces from OpenAI to Betalgo.Ranul.OpenAI.
  • Replace all occurrences of "OpenAi", "Openai", or any other variations with "OpenAI".

• Need Help?: If you encounter any issues, feel free to reach out via our Discord channel, Reddit channel, or GitHub discussions. We're happy to assist.

• Feedback Welcomed: If you notice any mistakes or missing name changes, please create an issue to let us know.

• Utilities Library Status: Please note that the Utilities library might remain broken for a while. I will focus on fixing it after completing the real-time API implementation.
