Google Releases LiteRT.js: A JavaScript Binding of LiteRT That Runs .tflite Models in Browsers via WebGPU

Jul 15, 2026

Google has released LiteRT.js, a JavaScript binding of its on-device inference library LiteRT, enabling .tflite model execution in browsers via WebAssembly, with support for XNNPACK on CPU, ML Drift over WebGPU, and experimental WebNN for NPUs. The runtime reports up to 3x gains over other web runtimes and 5–60x speedups on GPU or NPU compared to its own CPU path. Tensors are manually managed and must be explicitly deleted.

Why it matters: This enables efficient on-device AI inference directly in web browsers, potentially unlocking new classes of browser-based AI applications with significant performance improvements.
