OpenAI.Net
OpenAI library for .NET
C# .NET library for use with the OpenAI API.
This is community-maintained library.
This library supports .net core 6.0 and above.

Getting started
Install package Nuget package
Install-Package OpenAI.Net.Client
Register services using the provided extension methods
services.AddOpenAIServices(options => {
options.ApiKey = builder.Configuration["OpenAI:ApiKey"];
});
N.B We recommend using environment variables, configuration files or secret file for storing the API key securely. See here for further details.
Example Usage
You can view examples of a console, web application and Blazor app using the streaming API here.
You can also have a look at the Integration Tests for usage examples here.
Simple console app usage below.
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using OpenAI.Net;
namespace ConsoleApp
{
internal class Program
{
static async void Main(string[] args)
{
using var host = Host.CreateDefaultBuilder(args)
.ConfigureServices((builder, services) =>
{
services.AddOpenAIServices(options => {
options.ApiKey = builder.Configuration["OpenAI:ApiKey"];
});
})
.Build();
var openAi = host.Services.GetService<IOpenAIService>();
var response = await openAi.TextCompletion.Get("How long until we reach mars?");
if (response.IsSuccess)
{
foreach(var result in response.Result.Choices)
{
Console.WriteLine(result.Text);
}
}
else
{
Console.WriteLine($"{response.ErrorMessage}");
}
}
}
}
Configuring Http Client Options
The registration extension allows for configuration of the http client via the IHttpClientBuilder interface. This allows for adding a Polly retry policy for example. See example here.
services.AddOpenAIServices(options => {
options.ApiKey = builder.Configuration["OpenAI:ApiKey"];
},
(httpClientOptions) => {
httpClientOptions.AddPolicyHandler(GetRetryPolicy());
});
static IAsyncPolicy<HttpResponseMessage> GetRetryPolicy()
{
return HttpPolicyExtensions
.HandleTransientHttpError()
.WaitAndRetryAsync(3, retryAttempt => TimeSpan.FromSeconds(Math.Pow(2,
retryAttempt)));
}
Examples
Completion
var response = await service.TextCompletion.Get("Say this is a test",(o) => {
o.MaxTokens = 1024;
o.BestOf = 2;
});
Completion Stream
await foreach(var response in service.TextCompletion.GetStream("Say this is a test"))
{
Console.WriteLine(response?.Result?.Choices[0].Text);
}
Completion with array input
var prompts = new List<string>()
{
"Say this is a test",
"Say this is not a test"
};
var response = await service.TextCompletion.Get(prompts,(o) => {
o.MaxTokens = 1024;
o.BestOf = 2;
});
Chat
var messages = new List<Message>
{
Message.Create(ChatRoleType.System, "You are a helpful assistant."),
Message.Create(ChatRoleType.User, "Who won the world series in 2020?"),
Message.Create(ChatRoleType.Assistant, "The Los Angeles Dodgers won the World Series in 2020."),
Message.Create(ChatRoleType.User, "Where was it played?")
};
var response = await service.Chat.Get(messages,o => {
o.MaxTokens = 1000;
});
Chat Stream
var messages = new List<Message>
{
Message.Create(ChatRoleType.System, "You are a helpful assistant."),
