Even WebGL2 doesn't expose compute shaders, so any NN computations work by abusing the graphics pipeline, with many inefficiencies involved. Shader dispatch is more expensive, no access to local memory, no control over dispatch blocks. Hopefully the upcoming WebGPU specification will close these efficiency gaps.
