Intro

Welcome Flutteristas, AI enthusiasts, and everyone else! Are you ready to supercharge your apps with on-device AI capabilities? If so, you've come to the right place.

AubAI is a Flutter/Dart package that allows you to run on-device AI models.

It works on all major platforms. Don't take my word for it though, see for yourself. I have made YouTube videos that demonstrate AubAI in action. Check them out: YouTube.com/@BrutalCoding.

Designed with simplicity in mind, it's easy to use, and it's open source.

Do You Like This Project?

Assuming you have checked out AubAI, and you like it, there are several ways to show your appreciation:

  • Star this project.
    • It's a great way to show your appreciation, and it helps this project get more exposure.
  • Become a sponsor.
  • Contribute.
    • If you're a developer, you can contribute to this project by fixing bugs, adding features, or improving the documentation. See the CONTRIBUTING.md file for more information.
  • Spread the word.
    • Tell your friends, family, and colleagues about this project. The more people know about this project, the closer we get to the goal of making AI accessible to everyone without having to rely on any third-party services.

Consider becoming a sponsor. While the idea of this project is to make AI accessible to everyone, it comes at a cost, in terms of spending a lot of time on this project. My landlord doesn't accept GitHub stars as a form of payment, not yet at least. If you can afford it, please consider becoming a sponsor. It could be as little as $1 one time, $1 per month, or any other amount. Every little bit helps, both mentally and financially.

If you're a wealthy individual that was about to purchase a big luxury yacht, consider one less gold-plated knob on the steering wheel and use that money to add your name to the list of sponsors.

Werkloos

A Dutch word that perfectly describes my current situation: unemployed. But using that word in English might've made you skip this section, yet here you are. I'm glad you're still reading.

Recently, last September, the fintech startup I was working for had to shut down due to the challenging market conditions. While I'm currently looking for a new job, It's not easy to find a company that combines my passion for AI and Flutter.

I've decided to take a leap of faith and work on this project untill I find a new job, or until I run out of money (Jan-Feb 2024). Whichever comes first. Perhaps I'll find a way to make this project sustainable, while keeping it open source. I'm just going with the flow.

Supported Platforms

As I've previously mentioned in the intro, I have made YouTube videos that demonstrate AubAI in action. Check them out: YouTube.com/@BrutalCoding.

Setup

  1. Add the following to your pubspec.yaml file:
dependencies:
  aub_ai: ^1.0.0
  1. Run flutter pub get to install the package.

  2. Import the package in your Dart code:

import 'package:aub_ai/aub_ai.dart';
  1. Talk to the AI:
/// The output of the AI will be stored in this variable.
/// Can be used in a Text() widget, for example.
String outputByAI = '';

/// Example of how to use AubAI to talk to the AI.
Future<void> example() async {
  // Make sure that the model file is in the GGUF format.
  const String filePath = 'path/to/model.gguf';

  // The prompt to start the conversation with.
  const String promptByUser = 'Why is the sky blue?';

  // Pre-defined prompt templates are available.
  final promptTemplate = PromptTemplate.chatML().copyWith(
    prompt: promptByUser,
  );

  // THe main function that does all the magic.
  await talkAsync(
      filePathToModel: filePath,
      promptTemplate: promptTemplate,
      onTokenGenerated: (String token) {
        // This callback is called for every token generated by the AI.
        // A token can be seen as a partial word such as "hel" and "lo!".
        setState(() {
          outputByAI += token;
        });
      },
    );
}

Technical Details

AubAI is leveraging the power of llama.cpp. It's a C++ library that allows you to run AI models on your device. It's fast, it's lightweight, and it's open source. It's the perfect fit for AubAI.

While llama.cpp is a great library, it's not trivial to integrate it into a Flutter project. That's where AubAI comes in. It's a Flutter/Dart package that makes it easy to use llama.cpp in your Flutter project.

The vision of AubAI is to make AI accessible to everyone, and AI is more than just generating text. That's why AubAI is designed to be modular. Over time, more AI capabilities will be added to AubAI such as image generation, voice generation, and more.

Supported Model File Formats

  • x GGUF

Resources

If you're looking for a model file, you can find a couple here: HuggingFace.co.

At the time of writing, there are over 2300 models available. Some of them might be very good with math, others with coding, and others with poetry and some are good at everything. It's up to you to find the model that suits your use case for your app, or let your users choose a model like I did in the example app.
