Mojo GPU Syntax or specific GPU stdlib data types?

I'm looking forward to using MAX, I'm curious though outside of MAX how will the GPU syntax look? Will we need to use different data types other than SIMD that will be specific for GPU's like what is kind of done with cuda in C++? I'm hoping to be able to test this outside of AI paradigms that I couldn't use MAX for, like maybe improving the speed of opencv-like smoothing kernels or ray tracing.
