Generated C# SDK based on official OpenAI OpenAPI specification using NSwag

This package includes C# Source Generator which allows you to define functions natively through a C# interface, and also provides extensions that make it easier to call this interface later.
In addition to easy function implementation and readability, it generates Args classes, extension methods to easily pass a functions to API, and extension methods to simply call a function via json and return json.
Currently only System.Text.Json is supported.

public class Weather
    public string Location { get; set; } = string.Empty;

This repository contains the library with constants for all OpenAI constants(models/prices/context length and other).

using OpenAI.Constants;

string id = EmbeddingModels.Version3Small; // implicit conversion to string
double price = EmbeddingModels.Version3Small.GetPriceInUsd(tokens: 500); // 0.00001
EmbeddingModels.Version3Small.MaxInputTokens // 8191
EmbeddingModels.Version3Small.PricePerTokenInUsd // 0.00000002
