 ## A Note on Unit Tests
 The unit tests measure, among other things, the ANE speed-up factor. Since the device spec for this reference implementation is M1 or newer chips for the Mac and A14 and newer chips for the iPhone and iPad, the speed-up unit tests will print a warning message if executed on devices outside of this spec. Even if the model is generated using an out of spec Mac, the model should work as expected on in-spec devices.
