01What it can do
- Frontier scale (550B total, 55B active)
- MoE sparsity: compute cost close to a dense 55B
- 128k native context
- NVIDIA Open Model license (commercial use permitted)
- —~319 GB VRAM in Q4—requires multi-GPU H100/MI300 or a dedicated server
- —Gated on Hugging Face (click-through)
- —Beyond the reach of consumer hardware
04Install
Install Ollama for your OS. Check the model and its quantization before downloading. Start with 4096 tokens of context, then check placement with ollama ps. A command below is not proof that a test was run on your machine.
02Required memory
Approximate GPU VRAM required to run this model, including 4k tokens of context overhead. For a longer context, add ~1 GB per 8k-token increment.
What hardware do you need for Nemotron 3 Ultra?
To run Nemotron 3 Ultra locally with Q4 quantization, you need about 319 GB of VRAM. An option to compare: BOSGAME M5 128GB / 2TB (Ryzen AI Max+ 395) — this model exceeds this mini-PC's GPU capacity: choose a smaller model or suitable infrastructure.
