Can Mac Pro M2 Ultra 64 GB run Nemotron 3.5 Super VL 120B-A12B?

64 GB unified · 800 GB/s memory bandwidth · Nemotron 3.5 Super VL 120B-A12B has 120B parameters (12B active per token).

Short answer

No. It doesn't fit in memory.

Needs ≈62 GB but only ≈54 GB is available after the OS, other apps and Open WebUI.

Why it doesn’t fit

Even its smallest practical version (MXFP4) needs about 62 GB for the model, its context memory and the runtime. After macOS (≈6.0 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), Mac Pro M2 Ultra 64 GB has about 54 GB left, so it’s 7.9 GB short.

Ways to make it work

  • Close everything else

    Not enough on its own: with every other app closed it’s still about 4.9 GB short.

  • Pick a smaller model from the same family

  • Get more memory

    The same chip with 128 GB handles it: Excellent.

  • Check your exact setup

The same applies to every workload we rate (chat, coding questions, coding in a repository, agentic coding and long documents): they all need at least as much memory as chat.
