Together .NET SDK

Unofficial C# SDK for Together.ai with Semantic Kernel integration.

Introduction

Together.ai provides access to the latest open-source AI models through a simple API. This SDK offers:

• 🚀 Easy access to Together.ai's API from .NET applications
• 🧠 Seamless integration with Microsoft Semantic Kernel
• 🔧 Chat Completions, Text Generation, Embeddings and Image Generation
• 🌊 Both synchronous and streaming responses
• 🛠 Built-in function calling support

Installation

Choose the package(s) you need:

# Core API client
dotnet add package ManagedCode.Together

# Semantic Kernel integration
dotnet add package ManagedCode.Together.SemanticKernel

Usage Examples

Direct API Usage

using Together;

var client = new TogetherClient("YOUR_API_KEY");
var response = await client.ChatCompletions.CreateAsync(new ChatCompletionRequest 
{
    Model = "mistralai/Mistral-7B-Instruct-v0.1",
    Messages = new[] 
    { 
        new ChatCompletionMessage { Role = "user", Content = "Hello!" } 
    }
});

Semantic Kernel Integration

using Microsoft.SemanticKernel;
using Together.SemanticKernel;

// Initialize kernel with multiple Together.ai capabilities
var kernel = Kernel.CreateBuilder()
    .AddTogetherChatCompletion(
        "mistralai/Mistral-7B-Instruct-v0.1", 
        "YOUR_API_KEY"
    )
    .AddTogetherTextEmbeddingGeneration(
        "togethercomputer/m2-bert-80M-2k-retrieval",
        "YOUR_API_KEY"
    )
    .AddTogetherTextToImage(
        "stabilityai/stable-diffusion-xl-base-1.0",
        "YOUR_API_KEY"
    )
    .Build();

// Chat completion
var chatResult = await kernel.InvokePromptAsync("What is quantum computing?");

// Generate embeddings
var embeddingService = kernel.GetRequiredService<ITextEmbeddingGenerationService>();
var embeddings = await embeddingService.GenerateEmbeddingsAsync(
    ["What is quantum computing?"]
);

// Generate images
var imageService = kernel.GetRequiredService<ITextToImageService>();
var images = await imageService.GetImageContentsAsync(
    "A cat playing piano",
    new TogetherTextToImageExecutionSettings 
    {
        Height = 512,
        Width = 512
    }
);
