react-native-llm-mediapipe

react-native-llm-mediapipe enables developers to run large language models (LLMs) on iOS and Android devices using React Native. This package allows you to write JavaScript or TypeScript to handle LLM inference directly on mobile platforms.

Features

  • Run LLM Inference: Perform natural language processing tasks directly on mobile devices.
  • React Native Integration: Seamlessly integrates with your existing React Native projects.
  • JavaScript/TypeScript Support: Use familiar technologies to control LLM functionality.

Installation

To get started with react-native-llm-mediapipe, install the package using npm or yarn:

npm install react-native-llm-mediapipe

or

yarn add react-native-llm-mediapipe

Requirements

Before using this package, you must download or build the LLM model files necessary for its operation. Ensure these model files are properly configured and accessible by your mobile application. Some instructions can be found on the MediaPipe page. Or, see below for running a script that will download and convert the model files, automating the process

Building Models

As of 4/22/2024, MediaPipe supports four models for use on-device: Gemma 2B, Falcon 1B, StableLM 3B, and Phi-2. To download and convert the models, follow the instructions above or clone this (react-native-llm-mediapipe) repo, and follow the instructions here.

Usage

The primary functionality of this package is accessed through the useLlmInference() hook. This hook provides a generateResponse function, which you can use to process text prompts. Here is a basic example of how to use it in a React Native app:

import React, { useState } from 'react';
import { View, TextInput, Button, Text } from 'react-native';
import { useLlmInference } from 'react-native-llm-mediapipe';

const App = () => {
  const [prompt, setPrompt] = useState('');
  const { generateResponse } = useLlmInference();

  const handleGeneratePress = async () => {
    const response = await generateResponse(prompt);
    alert(response); // Display the LLM's response
  };

  return (
    <View style={{ padding: 20 }}>
      <TextInput
        style={{
          height: 40,
          borderColor: 'gray',
          borderWidth: 1,
          marginBottom: 10,
        }}
        onChangeText={setPrompt}
        value={prompt}
        placeholder="Enter your prompt here"
      />
      <Button title="Generate Response" onPress={handleGeneratePress} />
    </View>
  );
};

export default App;

In addition, you can access partial results by supplying a callback to generateResponse()

   const response = await llmInference.generateResponse(
      prompt,
      (partial) => {
        setPartialResponse((prev) => prev + partial));
      }
    );
