Can I run Nemotron 3 Ultra on Apple M3 Ultra (80-core GPU)?

Yes, but only just.best quant: Q4_K_M

This one is close. The answer rests on a file size we calculated from the parameter count rather than measured, and it leaves 17.9 GB spare once the weights, a 2K context and runtime overhead are counted. A 10% error in that size changes the verdict, so treat it as a maybe and test before you buy.
