Model Card
Nemotron 3 Nano Omni is an open multimodal model from NVIDIA that unifies text, image, video, and audio understanding in a single inference pass. Built on a 30B-parameter hybrid Mamba-Transformer Mixture-of-Experts architecture with only ~3B active parameters per token, it delivers strong reasoning at small-model inference costs.
It tops six leaderboards across document intelligence (MMLongBench-Doc, OCRBenchV2), video and audio understanding (WorldSense, DailyOmni, VoiceBench), and achieves the highest throughput of any benchmarked model — open or closed — on MediaPerf's video tasks, with up to 9x higher throughput than comparable open omni models.
Designed as a multimodal perception sub-agent in agentic systems, it excels at document reasoning, GUI-based computer use, speech transcription, and audio-video analysis — replacing fragmented multi-model pipelines with a single call. Supports up to 256K context with an optional reasoning mode.
