Generative CS

Generative AI library for .NET 9.0 with built-in OpenAI ChatGPT and Google Gemini API clients and support for C# function calling via reflection.

Supported Features

OpenAI

Gemini

Miscellaneous

Installation

.NET CLI

dotnet add package ChatAIze.GenerativeCS

Package Manager Console

Install-Package ChatAIze.GenerativeCS

Clients

Single Instance

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.

Chat Completion

Simple Prompt

using ChatAIze.GenerativeCS.Clients;

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

Console.WriteLine(response);

Streamed Prompt

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);
}

Chat

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);
}

Streamed Chat

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);

    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).

Embeddings

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");
string base64Embedding = await client.GetBase64EmbeddingAsync("The quick brown fox jumps over the lazy dog");

Audio

Text-to-Speech

Synthesize to File

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");

Speech-to-Text

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);

Translate From File

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);

Moderation

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

Options

[!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;

Additional Features

Time Awareness

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),
};

Limits

Message Limit

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,
};

Character Limit

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,
};

Message Pinning

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);
