> WASM-powered onnx runtime background removal tool Yes it's slow because they will most likely execute on CPU (for sure on iOS). WebGPU is still not enabled on safari and WebNN is not even supported anywhere (so that you can use NPU provider). ONNXRuntime is not even the most optimised when running natively (instead of WASM) on iOS, e.g. doesn't support MPS provider (GPU) and NPU provider (via CoreML) implements only subset operators (last time I tried). Safari also provide limitation on WASM memory usage In practice when you want the best performance you would have to use native app and CoreML with NPU provider and model architecture optimized for NPU. On iOS for now big limitation is available RAM, but even my iPhone 13 mini has exactly the same fast NPU as on my Macbook M2 Max when tested it's having similar speed to running on GPU.
