Installation

Install Mistral.SDK via the NuGet package manager:

PM> Install-Package Mistral.SDK

API Keys

You can load the API Key from an environment variable named MISTRAL_API_KEY by default. Alternatively, you can supply it as a string to the MistralClient constructor.

IHttpClientFactory

The MistralClient can optionally take an IHttpClientFactory, which allows you to control elements such as retries and timeouts.

Usage

To start using the Mistral API, simply create an instance of the MistralClient class.

Examples

Non-Streaming Call

Here's an example of a non-streaming call to the mistral-medium completions endpoint (other options are available and documented, but omitted for brevity):

var client = new MistralClient();
var client = new MistralClient();
var request = new ChatCompletionRequest(
    //define model - required
    ModelDefinitions.MistralMedium,
    //define messages - required
    new List<ChatMessage>()
{
    new ChatMessage(ChatMessage.RoleEnum.System, 
        "You are an expert at writing sonnets."),
    new ChatMessage(ChatMessage.RoleEnum.User, 
        "Write me a sonnet about the Statue of Liberty.")
}, 
    //optional - defaults to false
    safePrompt: true, 
    //optional - defaults to 0.7
    temperature: 0, 
    //optional - defaults to null
    maxTokens: 500, 
    //optional - defaults to 1
    topP: 1, 
    //optional - defaults to null
    randomSeed: 32);
var response = await client.Completions.GetCompletionAsync(request);
Console.WriteLine(response.Choices.First().Message.Content);

Streaming Call

The following is an example of a streaming call to the mistral-medium completions endpoint:

var client = new MistralClient();
var request = new ChatCompletionRequest(
    ModelDefinitions.MistralMedium, 
    new List<ChatMessage>()
{
    new ChatMessage(ChatMessage.RoleEnum.System, 
        "You are an expert at writing sonnets."),
    new ChatMessage(ChatMessage.RoleEnum.User, 
        "Write me a sonnet about the Statue of Liberty.")
});
var results = new List<ChatCompletionResponse>();
await foreach (var res in client.Completions.StreamCompletionAsync(request))
{
    results.Add(res);
    Console.Write(res.Choices.First().Delta.Content);
}

List Models

The following is an example of a call to list the available models:

var client = new MistralClient();

var response = await client.Models.GetModelsAsync();

Embeddings

The following is an example of a call to the mistral-embed embeddings model/endpoint:

var client = new MistralClient();
var request = new EmbeddingRequest(
    ModelDefinitions.MistralEmbed, 
    new List<string>() { "Hello world" }, 
    EmbeddingRequest.EncodingFormatEnum.Float);
var response = await client.Embeddings.GetEmbeddingsAsync(request);
