Usage

Initializing

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.PullModelAndEnsureSuccessAsync("all-minilm");

// 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<long>? context = null;
var enumerable = ollama.Completions.GenerateCompletionAsync("llama3", "answer 5 random words", stream: true);
await foreach (var response in enumerable)
{
    Console.WriteLine($"> {response.Response}");
    
    context = response.Context;
}

var lastResponse = await ollama.Completions.GenerateCompletionAsync("llama3", "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);
}
