NVIDIA Nemotron 3 Nano Omni

What is NVIDIA Nemotron 3 Nano Omni?

NVIDIA Nemotron 3 Nano Omni is an open omni-modal model: it sees, hears, watches and reads
— text, image, audio and video in, text out — from a single 30B-A3B mixture-of-experts that
activates only about 3B parameters per token. It is a Mamba-Transformer hybrid with a 256K
context, released under the NVIDIA Open Model Agreement, which permits commercial use. It
scores 67.04 on OCRBench V2, 72.2 on Video-MME, 47.4 on OSWorld and 89.39 on Speech IF.

Four input modalities in one 30B model that runs on a single RTX 5090 at NVFP4 (about
21 GB) is the notable part. The usual way to build an application that handles audio, video,
images and text is to chain three or four specialist models, each with its own deployment,
latency budget and failure mode. Nemotron 3 Nano Omni collapses that into one, which is why
its 47.4 on OSWorld — a computer-use benchmark that requires seeing a screen and acting on it
— is more interesting than the raw number suggests. There is no public per-token API price;
the cost is the hardware, which for a single-GPU deployment is unusually approachable for a
model of this breadth.
