NE Nemotron 3 Super 120B-A12B: RAM and VRAM requirements

Nemotron 3 Super 120B-A12B needs about 80.3 GB to run at Q4_K_M (the Q4_K_M GGUF file is ~76.87 GB to download; KV cache and overhead add the rest), or about 123.1 GB at Q8_0. The lightest hardware that runs it is Apple M4 Max (128GB).

Nemotron 3 family · 120B params (Mixture-of-Experts: activates only 12B of 120B params per token, so generation is faster than the total size suggests) · released Mar 2026.

How context length changes it

4k context ~80.3 GB 32k context ~98.7 GB 128k context ~161.8 GB

Longer context grows the KV cache, which for Nemotron 3 Super 120B-A12B is sized by its 12B active params, not the full 120B. It needs ~80.3 GB at 4k and ~161.8 GB at 128k.

FAQ

How much VRAM or RAM does Nemotron 3 Super 120B-A12B need?

At Q4_K_M, Nemotron 3 Super 120B-A12B needs about 80.3 GB (weights ~76.87 GB + KV cache + overhead) at a 4k context. At Q8_0 budget ~123.1 GB.

What is the Q4_K_M GGUF file size of Nemotron 3 Super 120B-A12B?

The Q4_K_M GGUF file is about 76.87 GB to download, and the Q8_0 GGUF is about 119.65 GB. That is the weights file on disk; to run it you also need room for the KV cache and overhead, so budget ~80.3 GB of memory at Q4_K_M.

Can Nemotron 3 Super 120B-A12B run on a laptop?

Nemotron 3 Super 120B-A12B is large; you need a high-memory Mac or multi-GPU setup at Q4_K_M.

Is Nemotron 3 Super 120B-A12B cheaper to run because it is a MoE model?

It is faster, not lighter. Nemotron 3 Super 120B-A12B activates only 12B of 120B params per token (so it runs quickly), but all experts must stay in memory, so it still needs memory for the full 120B.

Can I use Nemotron 3 Super 120B-A12B commercially?

Conditionally. NVIDIA Nemotron Open Model License; check the terms for commercial use.

Understand the numbers

Short guides to the ideas behind Nemotron 3 Super 120B-A12B's memory and quant figures.

MoE: 120B total / 12B active, hybrid Latent-MoE (Mamba-2 + MoE + multi-token-prediction layers), NVFP4-trained. 256K context by default, up to 1M. Needs a multi-GPU rig or a high-memory Mac Studio even at Q4. Sizes from unsloth's UD-quant GGUF repo. NVIDIA Nemotron Open Model License.
