Nemotron 3 Nano Omni — NVIDIA 的本地 AI 模型

作者: Jakub Rusinowski · 最后更新:

The first mainstream omni-modal open model that a single consumer GPU can actually hold: text, image, speech and video in, text out, at 3B active parameters from a 30B MoE. 260K context under the NVIDIA Open Model License, which permits commercial use. The efficiency ratio here is the story — video understanding at roughly the per-token cost of a 3B dense model.

变体

Nemotron 3 Nano Omni 最小的变体在 Q4_K_M 下约需 19 GB 显存——量化权重加框架开销,不含 KV 缓存。

我的 GPU 能运行 Nemotron 3 Nano Omni 吗?

Nemotron 3 Nano Omni — 常见问题

How much VRAM does Nemotron 3 Nano Omni need?

Nemotron 3 Nano Omni needs about 19 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Nemotron 3 Nano Omni 30B-A3B (19 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.

Can I run Nemotron 3 Nano Omni on an RTX 4090 (24 GB)?

Yes — Nemotron 3 Nano Omni runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.

What quantization should I use for Nemotron 3 Nano Omni?

Q4_K_M is the best balance of quality and VRAM for Nemotron 3 Nano Omni in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.

How do I run Nemotron 3 Nano Omni with Ollama?

Nemotron 3 Nano Omni has no local Ollama tag — the published tag is cloud-hosted, so running it sends your prompts to a hosted GPU rather than your own machine.
