This library enables state-of-the-art machine learning models to run directly in the browser using JavaScript, eliminating the need for server-side infrastructure. It targets web developers and researchers looking to integrate advanced NLP, computer vision, audio, and multimodal capabilities into client-side applications, offering a familiar API to the Hugging Face Python library.

How It Works

Transformers.js leverages ONNX Runtime for efficient execution of models within the browser. Models are converted to the ONNX format, a widely supported intermediate representation, using 🤗 Optimum. This approach allows for broad model compatibility and optimized performance, with support for both CPU (via WebAssembly) and GPU (via WebGPU) execution.

Quick Start & Requirements

• Install via NPM: npm i @huggingface/transformers
• Can also be used via CDN or static hosting.
• Requires a modern browser supporting WebGPU for GPU acceleration.
• Official documentation: https://huggingface.co/docs/transformers.js/index
• Examples: https://huggingface.co/docs/transformers.js/samples

Highlighted Details

• Supports a wide range of tasks including text classification, object detection, speech recognition, and text-to-speech.
• Offers GPU acceleration via WebGPU for improved performance.
• Supports model quantization (e.g., q4, q8) for reduced bandwidth and faster inference in resource-constrained environments.
• Provides a pipeline API mirroring the Python library for ease of use.

Maintenance & Community

• Developed and maintained by Hugging Face.
