The OpenAI .NET library has officially exited beta and is now available at version 2.0.0, indicating its readiness for production use.

This latest version introduces several breaking changes, including renamed options for the OpenAI client and updated method names that developers need to consider when upgrading.

The library provides developers with access to the OpenAI REST API, enabling the creation of AI-driven applications with features such as Assistants v2 and Chat Completions.

Key functionalities of the library include chat completions, text embeddings, image generation, audio transcription, and advanced assistant capabilities like retrieval augmented generation (RAG).

Additional key features include support for GPT-4o, extensibility for community-driven enhancements, and both synchronous and asynchronous APIs, along with compatibility with .NET Standard 2.0.

Alongside the OpenAI .NET library, Microsoft also offers the Semantic Kernel SDK, which provides access to multiple large language models across various programming languages such as C#, Java, Python, and JavaScript.

Developers are encouraged to explore both the OpenAI .NET library and the Semantic Kernel SDK to determine which option best suits their project needs.

Integration of the library into projects is straightforward, with developers able to use NuGet by executing the command: `dotnet add package OpenAI`.
