About
NVIDIA Nemotron 3 Nano Omni is an open-weight 30B hybrid MoE multimodal model (3B active parameters) that natively accepts text, image, video, and audio inputs in a single inference loop. Built on a hybrid Mamba-Transformer architecture with 23 Mamba-2 layers, 23 MoE layers (128 experts, 6+1 active), and 6 GQA layers, plus Conv3D video layers and Efficient Video Sampling (EVS). Delivers up to 9x higher throughput than comparable omni models. Supports a 256K context window and a 16,384 reasoning budget. Open weights, datasets, and training recipes released under a permissive license.
Nemotron 3 Nano Omni is an open-weight model in the Nemotron 3 family. The structured metadata tracks a 262k-token context window, multimodal input, and audio. This page tracks provider routes through OpenRouter, with the cheapest tracked route listed at free input and free output per 1M tokens. Headline tracked benchmarks include MMLU PRO 71.8.
