A simple light-weight library that wraps the GPT-3 API with support for dependency injection.

Supported features include:

  • Completions
  • Edits
  • Files
  • Fine Tunes
  • Images
  • Embeddings
  • Moderations
  • Response streaming

Examples include:

  • Command line bot
  • Azure Function Twitter Webhook that responds to DMs
  • Blazor UI

Dependency Injection Quickstart

services.Configure<ChatGPTCredentials>(options =>
    options.ApiKey = "YOURAPIKEY";
    options.Organization = "YOURORGANIZATIONID";




services.AddHttpClient<IChatGPTClient, ChatGPTClient>();

Configure IChatGPTClient service:

services.AddScoped<IChatGPTClient, ChatGPTClient>();


GPT-3 Completions use models to answer a wide variety of tasks, including but not limited to classification, sentiment analysis, answering questions, etc.

Completion Quickstart

This shows a direct useage of the text-davinci-003 model without any prompts.

using Whetstone.ChatGPT;
using Whetstone.ChatGPT.Models;

. . .

IChatGPTClient client = new ChatGPTClient("YOURAPIKEY");

var gptRequest = new ChatGPTCompletionRequest
    Model = ChatGPTCompletionModels.Davinci,
    Prompt = "How is the weather?"

var response = await client.CreateCompletionAsync(gptRequest);


GPT-3 is not deterministic. One of the test runs of the sample above returned:

The weather can vary greatly depending on location. In general, you can expect temperatures to be moderate and climate to be comfortable, but it is always best to check the forecast for your specific area.

Completion Code Sample

A C# console application that uses completions is available at:

Whetstone.ChatGPT.CommandLineBot (chatgpt-marv)

This sample includes:

  • Authentication
  • Created a completion request using a prompt
  • Processing completion responses

Editing Quickstart

To use submit an edit completion request:

using Whetstone.ChatGPT;
using Whetstone.ChatGPT.Models;

. . .

IChatGPTClient client = new ChatGPTClient("YOURAPIKEY");

var gptEditRequest = new ChatGPTCreateEditRequest
    Input = "What day of the wek is it?",
    Instruction = "Fix spelling mistakes"

var response = await client.CreateEditAsync(gptEditRequest);


One of the test runs returned:

What day of the week is it?

File Quickstart

How to create a upload a new fine tuning file.

List<ChatGPTFineTuneLine> tuningInput = new()
    new ChatGPTFineTuneLine("<PROMPT>", "<COMPLETION>"),
    new ChatGPTFineTuneLine("<PROMPT>", "<COMPLETION>"),
    . . .

byte[] tuningText = tuningInput.ToJsonLBinary();

string fileName = "finetuningsample.jsonl";

ChatGPTUploadFileRequest? uploadRequest = new ChatGPTUploadFileRequest
    File = new ChatGPTFileContent
        FileName = fileName,
        Content = tuningText

ChatGPTFileInfo? uploadedFileInfo;
using (IChatGPTClient client = new ChatGPTClient("YOURAPIKEY"))
    uploadedFileInfo = await client.UploadFileAsync(uploadRequest);

Fine Tuning Quickstart

Once the file has been created, get the fileId, and reference it when creating a new fine tuning.

using (IChatGPTClient client = new ChatGPTClient("YOURAPIKEY"))
  var fileList = await client.ListFilesAsync();
  var foundFile =  fileList.Data.First(x => x.Filename.Equals("finetuningsample.jsonl"));

  ChatGPTCreateFineTuneRequest tuningRequest = new ChatGPTCreateFineTuneRequest
     TrainingFileId = foundFile.Id

  ChatGPTFineTuneJob? tuneResponse = await client.CreateFineTuneAsync(tuningRequest);

  string fineTuneId = tuneResponse.Id;


Processing the fine tuning request will take some time. Once it finishes, the Status will report "succeeded" and it's ready to be used in a completion request.

using (IChatGPTClient client = new ChatGPTClient("YOURAPIKEY"))
  ChatGPTFineTuneJob? tuneResponse = await client.RetrieveFineTuneAsync("FINETUNEID");

    var gptRequest = new ChatGPTCompletionRequest
      Model = ChatGPTCompletionModels.Davinci,
      Prompt = "How is the weather?"

    var response = await client.CreateCompletionAsync(gptRequest);


Image Quickstart

Here's an example that generates a 1024x1024 image.

ChatGPTCreateImageRequest imageRequest = new()
    Prompt = "A sail boat",
    Size = CreatedImageSize.Size1024,
    ResponseFormat = CreatedImageFormat.Base64

using (IChatGPTClient client = new ChatGPTClient("YOURAPIKEY"))
    ChatGPTImageResponse? imageResponse = await client.CreateImageAsync(imageRequest);

    var imageData = imageResponse?.Data[0];

    if (imageData != null)
        byte[] imageBytes = await client.DownloadImageAsync(imageData);
