The official .NET library for accessing the OpenAI REST API, generated from the OpenAPI specification in collaboration with Microsoft. It provides typed clients for chat completions, responses, embeddings, image generation, audio transcription, and assistants with RAG support.

Use cases

• call the OpenAI API from a C# application
• stream chat completions in .NET
• generate text embeddings with dotnet
• transcribe audio using OpenAI from C#
• build RAG assistants in .NET
• use OpenAI with dependency injection in ASP.NET
• connect to Azure OpenAI from .NET

When to choose

• you are building a .NET application that needs OpenAI models
• you want an officially supported, typed client instead of raw HTTP calls
• you need Azure OpenAI compatibility from C#

When to avoid

• you use Python, Node.js, or another non-.NET language
• you need a provider-agnostic LLM client for multiple vendors
• you only need raw REST access and prefer a lightweight HTTP client
