Apple AMX is a private extension. It is not documented and not exposed to the developer. You have to use system-provided HPC and ML libraries to take advantage of the AMX units. This gives Apple the freedom to iterate and change implementation details at any time without breaking backwards compatibility.
I am sure they will support open standards in time as they mature, but for now there is little advantage in doing so. Not to mention that open standards are far from being a universal panacea. Remember Apple’s last serious involvement into open standards - OpenCL - which was promptly killed by Nvidia. Apple has since learned their lesson and focus on their own needs and technology stack first.
