Wow. So are you saying that you can have some array on the GPU that you setup with python via CuPy, then you call to the webbrowser and give it the pointer address for that GPU array, and the browser through WASM/WebGPU can access that same array? That sounds like a huge browser security hole.
Yea the security issue is why I'm pretty sure you can't do it on WGPU, but Vulkan and cupy can fully run locally so it doesn't have the same security concern.
