ChatGPT C# Integration

Overview

Just like many others I’ve been very excited about using ChatGPT.
Here is a simple example of how you can integrate your own project with ChatGPT.

Alternatively you can checkout this simple proof reader I made using ChatGPT.

Pre Requisites

You need to setup a billing account.

You need to create an API key.

Store your API Key securely.
Note, I store it at the machine level but you could do this at process or user level.
e.g. Windows PC

1
[System.Environment]::SetEnvironmentVariable('MY_OPEN_AI_API_KEY', 'your-sdk-api-key-value', 'Machine')

SDK

I opted to use a SDK to integrate with ChatGPT’s API.

Here is their list of official SDK’s.

I opted for a C# library, Betalgo/OpenAi by Betalgo.

using OpenAI.GPT3;
using OpenAI.GPT3.Managers;
using OpenAI.GPT3.ObjectModels.RequestModels;
using OpenAI.GPT3.ObjectModels;

var apiKey = Environment.GetEnvironmentVariable(
    "MY_OPEN_AI_API_KEY", EnvironmentVariableTarget.Machine);

var openAIService = new OpenAIService(
    new OpenAiOptions() { ApiKey = apiKey });

var request = new CompletionCreateRequest
{
    Prompt = "Give me a list of books on AI",
    Model = Models.TextDavinciV3,
    MaxTokens = 1000,
};

var result = await _openAIService.Completions.CreateCompletion(request);

Console.WriteLine(result.Choices.FirstOrDefault().Text);
