Microsoft is heralding the arrival of an official OpenAI library for .NET developers. The OpenAI library supports the complete OpenAI API and OpenAI’s latest flagship model, GPT-4o, which can reason across audio, vision, and text in real time.
Announced June 6 and available now in a first beta, the OpenAI .NET API library is accessible from NuGet.
Resulting from Microsoft’s collaboration with OpenAI, the OpenAI .NET API library provides sync and async access to the OpenAI REST API from .NET applications. It supports capabilities including Assistants v2, for building AI assistants within applications, and Chat Completions, for taking a list of messages as input and returning a model message. The library includes extensibility that enables the community to build libraries on top and access to streaming completions via IAsyncEnumerable<T>.
