Nemotron 3 Super 120B-A12B — 显存、速度与本地部署

作者: Jakub Rusinowski · 最后更新:

120B total / 12B active MoE. The low active-parameter count means throughput closer to a 12B model than a 120B one, but the full weight set still has to be resident — roughly 65 GB at Q4_K_M, so dual RTX 3090/4090 or a single 80GB datacenter card. Q8_0 and BF16 tags are published for workstations with more headroom. NVIDIA releases open training data and recipes with this family, which is unusual among open-weight releases.

Nemotron 3 Super 120B-A12B 在 Q4_K_M 下约需 73 GB 显存——量化权重加框架开销,不含 KV 缓存。在 Apple Silicon 上,这部分来自统一内存。

我的 GPU 能运行 Nemotron 3 Super 120B-A12B 吗?

Nemotron 3 Super 120B-A12B — 常见问题

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

About 73 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.

Does Nemotron 3 Super 120B-A12B run on an RTX 4090 (24 GB)?

No. Nemotron 3 Super 120B-A12B needs about 73 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.

How do I run Nemotron 3 Super 120B-A12B locally?

Install Ollama and run `ollama run nemotron-3-super:120b-a12b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
