Can I run gpt-oss-120b on H100 80GB SXM?
Probably partially, with CPU offload.best quant:
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.
75.9 GB of weights, plus 3.6 GB for the software that runs it and the smallest conversation it can hold, comes to 79.5 GB against the 78.8 GB this 80 GB device leaves free.
