LiteRT.js, Google's high performance Web AI Inference

LiteRT.js is a JavaScript binding of LiteRT designed to run AI models directly in web browsers, offering enhanced user privacy, zero server costs, and low latency by performing ML and AI model inference locally. It serves as an evolution from TensorFlow.js, providing smoother deployment for existing .tflite models by leveraging WebAssembly and native hardware acceleration, including XNNPACK for CPU, ML Drift for GPU, and the emerging WebNN for NPUs. The initial release includes a new npm package and demos, showcasing integration capabilities for web developers using JavaScript or TypeScript for tasks like text generation, object detection, and audio processing. LiteRT.js supports PyTorch conversion, tailored quantization, and high-performance inference across CPU, GPU, and NPU backends, delivering significant speed improvements over other web runtimes. The framework's integration with Ultralytics' YOLO models demonstrates its real-world application in real-time object detection and image processing. As LiteRT.js continues to develop, future plans include advancing WebNN integration and enhancing support for on-device generative AI.
