OpenAI

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.

Usage

using tryAGI.OpenAI; public enum Unit { Celsius, Fahrenheit, } public class Weather { public string Location { get; set; } = string.Empty; public double Temperature { get; set; } public Unit Unit { get; set; } public string Description { get; set; } = string.Empty; } [OpenAiFunctions] public interface IWeatherFunctions { [Description("Get the current weather in a given location")] public Task<Weather> GetCurrentWeatherAsync( [Description("The city and state, e.g. San Francisco, CA")] string location, Unit unit = Unit.Celsius, CancellationToken cancellationToken = default); } public class WeatherService : IWeatherFunctions { public Task<Weather> GetCurrentWeatherAsync(string location, Unit unit = Unit.Celsius, CancellationToken cancellationToken = default) { return Task.FromResult(new Weather { Location = location, Temperature = 22.0, Unit = unit, Description = "Sunny", }); } } var service = new WeatherService(); using var httpClient = new HttpClient(); var api = new OpenAiApi(apiKey, httpClient); var result = await api.CreateChatCompletionAsync(new CreateChatCompletionRequest { Messages = new List<ChatCompletionRequestMessage> { "You are a helpful weather assistant.".AsSystemMessage(), "What's the weather like today?".AsUserMessage(), }, Functions = service.AsFunctions(), Function_call = Function_call4.Auto, Model = "gpt-3.5-turbo-0613", }); // ... var resultMessage = result.GetFirstChoiceMessage(); var functionArgumentsJson = resultMessage.Function_call?.Arguments ?? string.Empty; var json = await service.CallGetCurrentWeatherAsync(functionArgumentsJson); // or just get arguments var args = service.AsGetCurrentWeatherAsyncArgs(functionArgumentsJson);
