Introducing NVIDIA Nemotron 3 Nano Omni: Long-Context Multimodal Intelligence for Documents, Audio and Video Agents

Back to Articles

NVIDIA Nemotron 3 Nano Omni is a new omni-modal understanding model built for real-world document analysis, multiple image reasoning, automatic speech recognition, long audio-video understanding, agentic computer use, and general reasoning.

It extends the Nemotron multimodal line from a strong vision-language system to a broader text + image + video + audio model.

Nemotron 3 Nano Omni delivers best-in-class accuracy on complex document intelligence leaderboards such as MMlongbench-Doc, OCRBenchV2, while also leading in video and audio leaderboards like WorldSense and DailyOmni. It achieves top accuracy on VoiceBench for audio understanding and ranks as the most cost‑efficient open video understanding model on MediaPerf.

Under the hood, it combines the Nemotron 3 hybrid Mamba-Transformer Mixture-of-Experts backbone with a C-RADIOv4-H vision encoder and Parakeet-TDT-0.6B-v2 audio encoder.
