## What it is
An unofficial C#/.NET SDK wrapping the OpenAI API, covering chat completions (GPT-3.5/4), DALL-E image generation, embeddings, moderation, and audio transcription/TTS. The original library is frozen at v1.11; it was adopted by Microsoft as the basis for the official OpenAI .NET library (v2+ on NuGet).

## Use cases
- call the openai api from c#
- use gpt-4 chat completions in a .net app
- generate images with dall-e from dotnet
- transcribe audio to text in c#
- get embeddings for text in .net
- connect to azure openai from c#

## When to choose
- you're on .NET Framework 4.7.2+ or .NET Core 3.0+ and want a simple OpenAI wrapper
- you need the legacy v1.x API surface or Azure OpenAI support in the original wrapper
- you want a mature, widely used community SDK with streaming chat support

## When to avoid
- you want the actively maintained official SDK - use the Microsoft OpenAI .NET library (v2+) instead
- you need coverage of the newest OpenAI endpoints and models
- you're not working in C#/.NET
