OpenAI-DotNet
A simple C# .NET client library for OpenAI to use though their RESTful API. Independently developed, this is not an official library and I am not affiliated with OpenAI. An OpenAI API account is required.
Forked from OpenAI-API-dotnet. More context on Roger Pincombe's blog.
Requirements
- This library targets .NET 6.0 and above.
- It should work across console apps, winforms, wpf, asp.net, etc.
- It should also work across Windows, Linux, and Mac.
Getting started
Install from NuGet
Install package OpenAI-DotNet
from Nuget. Here's how via command line:
powershell:
Install-Package OpenAI-DotNet
dotnet:
dotnet add package OpenAI-DotNet

Authentication
There are 3 ways to provide your API keys, in order of precedence:
Warning
We recommended using the environment variables to load the API key instead of having it hard coded in your source. It is not recommended use this method in production, but only for accepting user credentials, local testing and quick start scenarios.
- Pass keys directly with constructor ⚠️
- Load key from configuration file
- Use System Environment Variables
Pass keys directly with constructor
Warning
We recommended using the environment variables to load the API key instead of having it hard coded in your source. It is not recommended use this method in production, but only for accepting user credentials, local testing and quick start scenarios.
using var api = new OpenAIClient("sk-apiKey");
Or create a OpenAIAuthentication
object manually
using var api = new OpenAIClient(new OpenAIAuthentication("sk-apiKey", "org-yourOrganizationId", "proj_yourProjectId"));
Load key from configuration file
Attempts to load api keys from a configuration file, by default .openai
in the current directory, optionally traversing up the directory tree or in the user's home directory.
To create a configuration file, create a new text file named .openai
and containing the line:
Note
Organization and project id entries are optional.
Json format
{
"apiKey": "sk-aaaabbbbbccccddddd",
"organizationId": "org-yourOrganizationId",
"projectId": "proj_yourProjectId"
}
Deprecated format
OPENAI_API_KEY=sk-aaaabbbbbccccddddd
OPENAI_ORGANIZATION_ID=org-yourOrganizationId
OPENAI_PROJECT_ID=proj_yourProjectId
You can also load the configuration file directly with known path by calling static methods in OpenAIAuthentication
:
- Loads the default
.openai
config in the specified directory:
using var api = new OpenAIClient(OpenAIAuthentication.LoadFromDirectory("path/to/your/directory"));
- Loads the configuration file from a specific path. File does not need to be named
.openai
as long as it conforms to the json format:
using var api = new OpenAIClient(OpenAIAuthentication.LoadFromPath("path/to/your/file.json"));
Use System Environment Variables
Use your system's environment variables specify an api key and organization to use.
- Use
OPENAI_API_KEY
for your api key. - Use
OPENAI_ORGANIZATION_ID
to specify an organization. - Use
OPENAI_PROJECT_ID
to specify a project.
using var api = new OpenAIClient(OpenAIAuthentication.LoadFromEnv());
Handling OpenAIClient and HttpClient Lifecycle
OpenAIClient
implements IDisposable
to manage the lifecycle of the resources it uses, including HttpClient
. When you initialize OpenAIClient
, it will create an internal HttpClient
instance if one is not provided. This internal HttpClient
is disposed of when OpenAIClient
is disposed of. If you provide an external HttpClient
instance to OpenAIClient
, you are responsible for managing its disposal.
- If
OpenAIClient
creates its ownHttpClient
, it will also take care of disposing it when you disposeOpenAIClient
. - If an external
HttpClient
is passed toOpenAIClient
, it will not be disposed of byOpenAIClient
. You must manage the disposal of theHttpClient
yourself.
Please ensure to appropriately dispose of OpenAIClient
to release resources timely and to prevent any potential memory or resource leaks in your application.
Typical usage with an internal HttpClient
:
using var api = new OpenAIClient();
Custom HttpClient
(which you must dispose of yourself):
using var customHttpClient = new HttpClient();
// set custom http client properties here
var api = new OpenAIClient(client: customHttpClient);
Azure OpenAI
You can also choose to use Microsoft's Azure OpenAI deployments as well.
You can find the required information in the Azure Playground by clicking the View Code
button and view a URL like this:
https://{your-resource-name}.openai.azure.com/openai/deployments/{deployment-id}/chat/completions?api-version={api-version}
your-resource-name
The name of your Azure OpenAI Resource.deployment-id
The deployment name you chose when you deployed the model.api-version
The API version to use for this operation. This follows the YYYY-MM-DD format.
To setup the client to use your deployment, you'll need to pass in OpenAIClientSettings
into the client constructor.
var auth = new OpenAIAuthentication("sk-apiKey");
var settings = new OpenAIClientSettings(resourceName: "your-resource-name", deploymentId: "deployment-id", apiVersion: "api-version");
using var api = new OpenAIClient(auth, settings);
Azure Active Directory Authentication
Authenticate with MSAL as usual and get access token, then use the access token when creating your OpenAIAuthentication
. Then be sure to set useAzureActiveDirectory to true when creating your OpenAIClientSettings
.
Tutorial: Desktop app that calls web APIs: Acquire a token
// get your access token using any of the MSAL methods
var accessToken = result.AccessToken;
var auth = new OpenAIAuthentication(accessToken);
var settings = new OpenAIClientSettings(resourceName: "your-resource", deploymentId: "deployment-id", apiVersion: "api-version", useActiveDirectoryAuthentication: true);
using var api = new OpenAIClient(auth, settings);
OpenAI API Proxy
Using either the OpenAI-DotNet or com.openai.unity packages directly in your front-end app may expose your API keys and other sensitive information. To mitigate this risk, it is recommended to set up an intermediate API that makes requests to OpenAI on behalf of your front-end app. This library can be utilized for both front-end and intermediary host configurations, ensuring secure communication with the OpenAI API.
Front End Example
In the front end example, you will need to securely authenticate your users using your preferred OAuth provider. Once the user is authenticated, exchange your custom auth token with your API key on the backend.
Follow these steps:
- Setup a new project using either the OpenAI-DotNet or com.openai.unity packages.
- Authenticate users with your OAuth provider.
- After successful authentication, create a new
OpenAIAuthentication
object and pass in the custom token with the prefixsess-
. - Create a new
OpenAIClientSettings
object and specify the domain where your intermediate API is located. - Pass your new
auth
andsettings
objects to theOpenAIClient
constructor when you create the client instance.
Here's an example of how to set up the front end:
var authToken = await LoginAsync();
var auth = new OpenAIAuthentication($"sess-{authToken}");
var settings = new OpenAIClientSettings(domain: "api.your-custom-domain.com");
using var api = new OpenAIClient(auth, settings);
This setup allows your front end application to securely communicate with your backend that will be using the OpenAI-DotNet-Proxy, which then forwards requests to the OpenAI API. This ensures that your OpenAI API keys and other sensitive information remain secure throughout the process.
Back End Example
In this example, we demonstrate how to set up and use OpenAIProxy
in a new ASP.NET Core web app. The proxy server will handle authentication and forward requests to the OpenAI API, ensuring that your API keys and other sensitive information remain secure.
- Create a new ASP.NET Core minimal web API project.
- Add the OpenAI-DotNet nuget package to your project.
- Powershell install:
Install-Package OpenAI-DotNet-Proxy
- Dotnet install:
dotnet add package OpenAI-DotNet-Proxy
- Manually editing .csproj:
<PackageReference Include="OpenAI-DotNet-Proxy" />
- Powershell install:
- Create a new class that inherits from
AbstractAuthenticationFilter
and override theValidateAuthentication
method. This will implement theIAuthenticationFilter
that you will use to check user session token against your internal server. - In
Program.cs
, create a new proxy web application by callingOpenAIProxy.CreateWebApplication
method, passing your customAuthenticationFilter
as a type argument. - Create
OpenAIAuthentication
andOpenAIClientSettings
as you would normally with your API keys, org id, or Azure settings.
public partial class Program
{
private class AuthenticationFilter : AbstractAuthenticationFilter
{
public override async Task ValidateAuthenticationAsync(IHeaderDictionary request)
{
await Task.CompletedTask; // remote resource call to verify token
// You will need to implement your own class to properly test
// custom issued tokens you've setup for your end users.
if (!request.Authorization.ToString().Contains(TestUserToken))
{
throw new AuthenticationException("User is not authorized");
}
}
}
public static void Main(string[] args)
{
var auth = OpenAIAuthentication.LoadFromEnv();
var settings = new OpenAIClientSettings(/* your custom settings if using Azure OpenAI */);
using var openAIClient = new OpenAIClient(auth, settings);
OpenAIProxy.CreateWebApplication<AuthenticationFilter>(args, openAIClient).Run();
}
}
Once you have set up your proxy server, your end users can now make authenticated requests to your proxy api instead of directly to the OpenAI API. The proxy server will handle authentication and forward requests to the OpenAI API, ensuring that your API keys and other sensitive information remain secure.
Models
List and describe the various models available in the API. You can refer to the Models documentation to understand what models are available and the differences between them.

}
// submit the tool outputs
run = await run.SubmitToolOutputsAsync(toolOutputs);
// waiting while run in Queued and InProgress
run = await run.WaitForStatusChangeAsync();
var messages = await run.ListMessagesAsync();
foreach (var message in messages.Items.OrderBy(response => response.CreatedAt))
{
Console.WriteLine($"{message.Role}: {message.PrintContent()}");
}
Thread Structured Outputs
Structured Outputs is the evolution of JSON mode. While both ensure valid JSON is produced, only Structured Outputs ensure schema adherence.
Important
- When using JSON mode, always instruct the model to produce JSON via some message in the conversation, for example via your system message. If you don't include an explicit instruction to generate JSON, the model may generate an unending stream of whitespace and the request may run continually until it reaches the token limit. To help ensure you don't forget, the API will throw an error if the string "JSON" does not appear somewhere in the context.
- The JSON in the message the model returns may be partial (i.e. cut off) if
finish_reason
is length, which indicates the generation exceeded max_tokens or the conversation exceeded the token limit. To guard against this, checkfinish_reason
before parsing the response.
First define the structure of your responses. These will be used as your schema. These are the objects you'll deserialize to, so be sure to use standard Json object models.
public class MathResponse
{
[JsonInclude]
[JsonPropertyName("steps")]
public IReadOnlyList<MathStep> Steps { get; private set; }
[JsonInclude]
[JsonPropertyName("final_answer")]
public string FinalAnswer { get; private set; }

Chat Structured Outputs
The evolution of Json Mode. While both ensure valid JSON is produced, only Structured Outputs ensure schema adherence.
Important
- When using JSON mode, always instruct the model to produce JSON via some message in the conversation, for example via your system message. If you don't include an explicit instruction to generate JSON, the model may generate an unending stream of whitespace and the request may run continually until it reaches the token limit. To help ensure you don't forget, the API will throw an error if the string "JSON" does not appear somewhere in the context.
- The JSON in the message the model returns may be partial (i.e. cut off) if
finish_reason
is length, which indicates the generation exceeded max_tokens or the conversation exceeded the token limit. To guard against this, checkfinish_reason
before parsing the response.
First define the structure of your responses. These will be used as your schema. These are the objects you'll deserialize to, so be sure to use standard Json object models.
public class MathResponse
{
[JsonInclude]
[JsonPropertyName("steps")]
public IReadOnlyList<MathStep> Steps { get; private set; }
[JsonInclude]
[JsonPropertyName("final_answer")]
public string FinalAnswer { get; private set; }
}
public class MathStep
{
[JsonInclude]
[JsonPropertyName("explanation")]
public string Explanation { get; private set; }
[JsonInclude]
[JsonPropertyName("output")]
public string Output { get; private set; }
}
To use, simply specify the MathResponse
type as a generic constraint when requesting a completion.
var messages = new List<Message>
{
new(Role.System, "You are a helpful math tutor. Guide the user through the solution step by step."),
new(Role.User, "how can I solve 8x + 7 = -23")
};
var chatRequest = new ChatRequest<MathResponse>(messages, model: new("gpt-4o-2024-08-06"));
var (mathResponse, chatResponse) = await OpenAIClient.ChatEndpoint.GetCompletionAsync<MathResponse>(chatRequest);
for (var i = 0; i < mathResponse.Steps.Count; i++)
{
var step = mathResponse.Steps[i];
Console.WriteLine($"Step {i}: {step.Explanation}");
Console.WriteLine($"Result: {step.Output}");
}
Console.WriteLine($"Final Answer: {mathResponse.FinalAnswer}");
chatResponse.GetUsage();
Chat Json Mode
Important
- When using JSON mode, always instruct the model to produce JSON via some message in the conversation, for example via your system message. If you don't include an explicit instruction to generate JSON, the model may generate an unending stream of whitespace and the request may run continually until it reaches the token limit. To help ensure you don't forget, the API will throw an error if the string "JSON" does not appear somewhere in the context.
- The JSON in the message the model returns may be partial (i.e. cut off) if
finish_reason
is length, which indicates the generation exceeded max_tokens or the conversation exceeded the token limit. To guard against this, checkfinish_reason
before parsing the response. - JSON mode will not guarantee the output matches any specific schema, only that it is valid and parses without errors.
var messages = new List<Message>
{
new Message(Role.System, "You are a helpful assistant designed to output JSON."),
new Message(Role.User, "Who won the world series in 2020?"),
};
var chatRequest = new ChatRequest(messages, Model.GPT4o, responseFormat: ChatResponseFormat.Json);
var response = await api.ChatEndpoint.GetCompletionAsync(chatRequest);
