using ChatAIze.GenerativeCS.Clients;

var openAIClient = new OpenAIClient("<OPENAI API KEY>");
var geminiClient = new GeminiClient("<GEMINI API KEY>");

Dependency Injection

using ChatAIze.GenerativeCS.Extensions;

builder.Services.AddOpenAIClient("<OPENAI API KEY>");
builder.Services.AddGeminiClient("<GEMINI API KEY>");

[!NOTE] By default, both OpenAIClient and GeminiClient services are registered as singleton. It's advised not to change global client options after the web application has already been launched. Use per-request options instead.

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
string response = await client.CompleteAsync("Write an article about Bitcoin.");

Console.WriteLine(response);

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
await foreach (string chunk in client.StreamCompletionAsync("Write an article about Bitcoin."))
{
    Console.Write(chunk);
}

using ChatAIze.GenerativeCS.Clients;
using ChatAIze.GenerativeCS.Models;

var client = new OpenAIClient("<OPENAI API KEY>");
var chat = new Chat();

while (true)
{
    string message = Console.ReadLine()!;
    chat.FromUser(message);

    string response = await client.CompleteAsync(chat);
    Console.WriteLine(response);
}

using ChatAIze.GenerativeCS.Clients;
using ChatAIze.GenerativeCS.Models;

var client = new OpenAIClient("<OPENAI API KEY>");

    chat.FromUser(message);

    await foreach (string chunk in client.StreamCompletionAsync(chat))
    {
        Console.Write(chunk);
    }
}

[!NOTE] Chatbot responses, function calls, and function results are automatically added to the chat. You don't need to and should not call chat.FromAssistant(...) manually, unless you want to inject custom messages (e.g. welcome message).

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
float[] vectorEmbedding = await client.GetEmbeddingAsync("The quick brown fox jumps over the lazy dog");

var client = new OpenAIClient("<OPENAI API KEY>");
await client.SynthesizeSpeechAsync("The quick brown fox jumps over the lazy dog", "speech.mp3");

Synthesize to Byte Array

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
byte[] speech = await client.SynthesizeSpeechAsync("The quick brown fox jumps over the lazy dog");

Transcript From File

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
string transcript = await client.TranscriptAsync("speech.mp3");

Transcript From Byte Array

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
byte[] audio = await File.ReadAllBytesAsync("speech.mp3");
string transcript = await client.TranscriptAsync(audio);

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
string translation = await client.TranslateAsync("speech.mp3");

Translate From Byte Array

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
byte[] audio = await File.ReadAllBytesAsync("speech.mp3");
string translation = await client.TranslateAsync(audio);

using ChatAIze.GenerativeCS.Clients;

var client = new OpenAIClient("<OPENAI API KEY>");
var result = await client.ModerateAsync("I am going to blow up your house in Minecraft.");

Console.WriteLine(result.IsFlagged); // true
Console.WriteLine(result.IsViolence); // true 
Console.WriteLine(result.ViolenceScore); // 0,908397912979126

[!NOTE] Per-request options take precedence over default client options.

[!TIP] If you use OpenAI client add:
using ChatAIze.GenerativeCS.Options.OpenAI;
If you use Gemini client add:
using ChatAIze.GenerativeCS.Options.Gemini;

You can configure both Gemini and OpenAI clients to be aware of the current date and time.

using ChatAIze.GenerativeCS.Options.OpenAI;
// or
using ChatAIze.GenerativeCS.Options.Gemini;

var options = new ChatCompletionOptions
{
    IsTimeAware = true,
    // other completion options
};

By default, GenerativeCS uses DateTime.Now, but you can change the source of current time by specifying custom TimeCallback

using ChatAIze.GenerativeCS.Options.OpenAI;
// or
using ChatAIze.GenerativeCS.Options.Gemini;

var options = new ChatCompletionOptions
{
    IsTimeAware = true,
    TimeCallback = () => new DateTime(2024, 1, 14),
};

The maximum number of messages sent in a single chat completion request. The oldest messages will be removed one by one until the limit is satisfied.

Pinned messages count toward the limit and have priority but are never truncated.
The limit does include function calls and results.
Function definitions are not considered messages.

using ChatAIze.GenerativeCS.Options.OpenAI;
// or
using ChatAIze.GenerativeCS.Options.Gemini;

var options = new ChatCompletionOptions
{
    MessageLimit = 10,
};

The maximum number of characters sent in a single chat completion request. The oldest messages will be removed one by one until the limit is satisfied.

Pinned messages count toward the limit and have priority but are never truncated.
The limit does include function calls and results.
Function definitions are not considered messages.

using ChatAIze.GenerativeCS.Options.OpenAI;
// or
using ChatAIze.GenerativeCS.Options.Gemini;

var options = new ChatCompletionOptions
{
    CharacterLimit = 10,
};

Messages can be pinned to ensure they stay in the chat even when message and character limits are exceeded.

using ChatAIze.GenerativeCS.Enums;
using ChatAIze.GenerativeCS.Models;

var chat = new Chat();

chat.FromUser("This will always be the first message", PinLocation.Begin);
chat.FromSystem("This message will never be truncated due to limits.", PinLocation.Automatic);
chat.FromUser("This will always be the last (most recent) message", PinLocation.End);
