• Sync and async APIs: These ensure developers have the flexibility to use synchronous or asynchronous patterns depending on their application’s needs.
  
• Streaming completions: Access to streaming completions via [iCODE]IAsyncEnumerable<T>[/iCODE], offering more dynamic interaction models.
  
• Quality-of-life improvements: Numerous improvements have been made throughout the beta cycle based on community feedback.

This official .NET library ensures a smooth and supported integration with OpenAI and Azure OpenAI. It also complements OpenAI’s official libraries for Python and TypeScript/JavaScript developers.

 

The library is open-source, developed, and supported on GitHub. It will be kept up to date with the latest features from OpenAI.

 

[HEADING=1]Sample code[/HEADING]

 

Here’s a quick look at how easy it is to use the OpenAI library in a .NET application. The following code snippet demonstrates how to create an OpenAI client and use it to complete a chat interaction:

 

 

using OpenAI.Chat;ChatClient client = new(   model: "gpt-4o",   apiKey: Environment.GetEnvironmentVariable("OPENAI_API_KEY"));ChatCompletion completion = client.CompleteChat("Say 'this is a test.'");Console.WriteLine($"[ASSISTANT]: {completion.Content[0].Text}");

 

[HEADING=1]Thank you to the .NET community[/HEADING]

 

This stable release wouldn’t have been possible without the continued support and feedback from the .NET community. Over the course of the beta, we’ve seen significant engagement and contributions that helped shape this release. We’re committed to continuing this collaboration as the library evolves.
