If you’ve trained or deployed a model recently, you’ve depended on an ML compiler — possibly several of them stacked on top of each other. PyTorch’s `torch.compile`, TensorRT, CoreML, XLA, TVM, Triton: all compilers, all solving variations of the same problem, all making surprisingly different architectural choices.

The interesting question isn’t “which is fastest?” — that depends on your hardware and workload. The interesting question is: **why do they look so different from each other?** Why does an NVIDIA TensorRT engine refuse to run on a different GPU generation while a CoreML model happily hops between the Neural Engine, GPU, and CPU on any Apple device shipped in the last five years? Why does JAX recompile your function the first time you call it while CoreML ships a fully baked binary?

These aren’t implementation accidents. They’re consequences of two fundamental design deci
