🚀 Quick Start

bash
npm install @browserai/browserai

OR

bash
yarn add @browserai/browserai

Basic Usage

import { BrowserAI } from '@browserai/browserai';

const browserAI = new BrowserAI();

browserAI.loadModel('llama-3.2-1b-instruct');

const response = await browserAI.generateText('Hello, how are you?');
console.log(response);

📚 Examples

Text Generation with Custom Parameters

const ai = new BrowserAI();
await ai.loadModel('llama-3.2-1b-instruct', {
  quantization: 'q4f16_1' // Optimize for size/speed
});

const response = await ai.generateText('Write a short poem about coding', {
  temperature: 0.8,
  maxTokens: 100
});

Chat with System Prompt

const ai = new BrowserAI();
await ai.loadModel('gemma-2b-it');

const response = await ai.generateText([
  { role: 'system', content: 'You are a helpful assistant.' },
  { role: 'user', content: 'What is WebGPU?' }
]);

Speech Recognition

const ai = new BrowserAI();
await ai.loadModel('whisper-tiny-en');

// Using the built-in recorder
await ai.startRecording();
const audioBlob = await ai.stopRecording();
const transcription = await ai.transcribeAudio(audioBlob);

Text-to-Speech

const ai = new BrowserAI();
await ai.loadModel('speecht5-tts');
const audioBuffer = await ai.textToSpeech('Hello, how are you today?');
// Play the audio using Web Audio API
const audioContext = new AudioContext();
const source = audioContext.createBufferSource();
audioContext.decodeAudioData(audioBuffer, (buffer) => {
  source.buffer = buffer;
  source.connect(audioContext.destination);
  source.start(0);
});
