Magenta.js is a collection of TypeScript libraries for running inference with pre-trained Magenta machine learning models directly in the browser via TensorFlow.js. It provides npm packages for music generation (MusicVAE, MelodyRNN, DrumsRNN), sketch drawing (SketchRNN), and image style transfer.

Use cases

  • generate music melodies in the browser with machine learning
  • run MusicVAE or MelodyRNN models client-side
  • create AI-assisted sketch drawings with SketchRNN
  • apply neural style transfer to images in a web app
  • build interactive creative AI demos in JavaScript
  • generate drum patterns with machine learning in the browser

When to choose

  • you want to run pre-trained generative music or art models entirely client-side in the browser
  • you need TensorFlow.js implementations of Magenta models via npm packages
  • you are building creative coding or interactive AI music/art web applications

When to avoid

  • you need to train models from scratch rather than run inference with pre-trained ones
  • you need server-side or high-performance native ML inference outside the browser
  • you need the latest Magenta models like RealTime/Lyria, which live in other Magenta projects
