OpenAI.ChatGPT 1.0.0

OpenAI Chat Completions (ChatGPT) client for .NET

This is a .NET client for the OpenAI Chat Completions API (ChatGPT). It allows you to use the API in your .NET applications. Also, the client supports streaming responses (like ChatGPT) via async streams.

Preparation

First, you need to create an OpenAI account and get an API key. You can do this at https://platform.openai.com/account/api-keys.

Installation

You can install the package via NuGet:

Install-Package OpenAI.ChatGPT

Then create an instance of OpenAIClient:

_client = new OpenAiClient("{YOUR_OPENAI_API_KEY}");

Simple usage of the Chat Completions API

string text = "Who are you?";
string response = await _client.GetChatCompletions(new UserMessage(text), maxTokens: 80);
Console.WriteLine(response);

Streaming response with async streams (like ChatGPT)

var text = "Write the world top 3 songs of Soul genre";
await foreach (string chunk in _client.StreamChatCompletions(new UserMessage(text), maxTokens: 80))
{
    Console.Write(chunk);
}

Continue dialog with ChatGPT (message history)

Use ThenAssistant and ThenUser methods to create a dialog:

ChatCompletionDialog dialog = 
    new UserMessage("How many meters are in a kilometer? Write just the number.") //the message from user
    .ThenAssistant("1000") // response from the assistant
    .ThenUser("Convert it to hex. Write just the number."); // the next message from user

await foreach (var chunk in _client.StreamChatCompletions(dialog, maxTokens: 80))
{
    Console.Write(chunk);
}

Or just send message history as a collection.

OpenAI Images API (text-to-image)

Generate image bytes

byte[] image = await _client.GenerateImageBytes("bicycle", "test", OpenAiImageSize._256);

Generate images uris

Uri[] uris = await _client.GenerateImagesUris("bicycle", "test", OpenAiImageSize._256, count: 2);

More examples see in the tests.
