# Ollama SDK for .NET 🦙
[](https://www.nuget.org/packages/Ollama/)

## Features 🔥
- Fully generated C# SDK based on [OpenAPI specification](https://github.com/davidmigloz/langchain_dart/blob/main/packages/ollama_dart/oas/ollama-curated.yaml) using [OpenApiGenerator](https://github.com/HavenDV/OpenApiGenerator)
- Automatic releases of new preview versions if there was an update to the OpenAPI specification
- Source generator to define tools natively through C# interfaces
- All modern .NET features - nullability, trimming, NativeAOT, etc.
- Support .Net Framework/.Net Standard 2.0
- Support for all Ollama API endpoints including chats, embeddings, listing models, pulling and creating new models, and more.
## Usage
### Initializing
```csharp
using var ollama = new OllamaApiClient();
var models = await ollama.Models.ListModelsAsync();
// Pulling a model and reporting progress
await foreach (var response in ollama.PullModelAsync("all-minilm", stream: true))
{
Console.WriteLine($"{response.Status}. Progress: {response.Completed}/{response.Total}");
}
// or just pull the model and wait for it to finish
await ollama.Models.PullModelAsync("all-minilm").EnsureSuccessAsync();
// Generating an embedding
var embedding = await ollama.Embeddings.GenerateEmbeddingAsync(
model: "all-minilm",
prompt: "hello");
// Streaming a completion directly into the console
// keep reusing the context to keep the chat topic going
IList? context = null;
var enumerable = ollama.Completions.GenerateCompletionAsync("llama3.2", "answer 5 random words");
await foreach (var response in enumerable)
{
Console.WriteLine($"> {response.Response}");
context = response.Context;
}
var lastResponse = await ollama.Completions.GenerateCompletionAsync("llama3.2", "answer 123", stream: false, context: context).WaitAsync();
Console.WriteLine(lastResponse.Response);
var chat = ollama.Chat("mistral");
while (true)
{
var message = await chat.SendAsync("answer 123");
Console.WriteLine(message.Content);
var newMessage = Console.ReadLine();
await chat.Send(newMessage);
}
```
### Tools
```csharp
using var ollama = new OllamaApiClient();
var chat = ollama.Chat(
model: "llama3.2",
systemMessage: "You are a helpful weather assistant.",
autoCallTools: true);
var service = new WeatherService();
chat.AddToolService(service.AsTools(), service.AsCalls());
try
{
_ = await chat.SendAsync("What is the current temperature in Dubai, UAE in Celsius?");
}
finally
{
Console.WriteLine(chat.PrintMessages());
}
```
```
> System:
You are a helpful weather assistant.
> User:
What is the current temperature in Dubai, UAE in Celsius?
> Assistant:
Tool calls:
GetCurrentWeather({"location":"Dubai, UAE","unit":"celsius"})
> Tool:
{"location":"Dubai, UAE","temperature":22,"unit":"celsius","description":"Sunny"}
> Assistant:
The current temperature in Dubai, UAE is 22°C.
```
```csharp
using CSharpToJsonSchema;
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;
}
[GenerateJsonSchema]
public interface IWeatherFunctions
{
[Description("Get the current weather in a given location")]
public Task 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 GetCurrentWeatherAsync(string location, Unit unit = Unit.Celsius, CancellationToken cancellationToken = default)
{
return Task.FromResult(new Weather
{
Location = location,
Temperature = 22.0,
Unit = unit,
Description = "Sunny",
});
}
}
```
## Credits
Icon and name were reused from the amazing [Ollama project](https://github.com/jmorganca/ollama).
The project was forked from [this repository](https://github.com/awaescher/OllamaSharp),
after which automatic code generation was applied based on [this OpenAPI specification](https://github.com/davidmigloz/langchain_dart/blob/main/packages/ollama_dart/oas/ollama-curated.yaml)
(in the future it will be replaced by the official one, if one appears)
