Nemotron 3 Nano Omni
Nemotron 3 Nano Omni combines a Nemotron 3 Nano language backbone with image and audio encoders for unified multimodal reasoning. It accepts text, images, audio, and video and produces textual answers, summaries, and tool calls. The model targets document understanding, video question answering, and spoken-input agents while avoiding a separate model for each input type. The backbone has approximately 31B parameters with about 3B active; encoder parameters and multimodal tokens also contribute to memory and context usage.
