OllamaSharp 3.0.0

OllamaSharp 🦙

OllamaSharp is a .NET binding for the Ollama API, making it easy to interact with Ollama using your favorite .NET languages.

Features

• Intuitive API client: Set up and interact with Ollama in just a few lines of code.
• API endpoint coverage: Support for all Ollama API endpoints including chats, embeddings, listing models, pulling and creating new models, and more.
• Real-time streaming: Stream responses directly to your application.
• Progress reporting: Get real-time progress feedback on tasks like model pulling.
• API Console: A ready-to-use API console to chat and manage your Ollama host remotely

Usage

OllamaSharp wraps every Ollama API endpoint in awaitable methods that fully support response streaming.

The follow list shows a few examples to get a glimpse on how easy it is to use. The list is not complete.

Initializing

// set up the client
var uri = new Uri("http://localhost:11434");
var ollama = new OllamaApiClient(uri);

// select a model which should be used for further operations
ollama.SelectedModel = "llama3.1:8b";

Listing all models that are available locally

var models = await ollama.ListLocalModels();

Pulling a model and reporting progress

await foreach (var status in ollama.PullModel("llama3.1:405b"))
    Console.WriteLine($"{status.Percent}% {status.Status}");

Generating a completion directly into the console

await foreach (var stream in ollama.Generate("How are you today?"))
    Console.Write(stream.Response);

Building interactive chats

var chat = new Chat(ollama);
while (true)
{
    var message = Console.ReadLine();
    await foreach (var answerToken in chat.Send(message))
        Console.Write(answerToken);
}
// messages including their roles and tool calls will automatically be tracked within the chat object
// and are accessible via the Messages property

Api Console

This project ships a full-featured demo console for all endpoints the Ollama API is exposing.

This is not only a great resource to learn about OllamaSharp, it can also be used to manage and chat with the Ollama host remotely. Image chat is supported for multi modal models.
