 WebGPU enables web developers to harness GPU hardware for high-performance computations. The ONNX Runtime 1.17 release introduces the official launch of the WebGPU execution provider in ONNX Runtime Web, allowing sophisticated models to run entirely and efficiently within the browser (see the [list of WebGPU browser compatibility](https://github.com/gpuweb/gpuweb/wiki/Implementation-Status)). This advancement, demonstrated by the effective execution of models such as SD-Turbo, unlocks new possibilities in scenarios where CPU-based in-browser machine learning faces challenges in meeting performance standards.
