Can I run gpt-oss-120b on Apple M5 Pro (20-core GPU)?
Probably not, though offload might cover it.
This one is close. The answer rests on a file size we calculated from the parameter count rather than measured. A 10% error in that size changes the verdict, so treat it as a maybe and test before you buy.
