Nemotron 3 Nano Omni 30B A3B Reasoning adds native audio input to NVIDIA's Nano line. The model handles text, images, video, and audio in one reasoning checkpoint. It activates 3 billion of 30 billion parameters.
The official model card uses custom multimodal classes and custom code. That limits serving stacks built only around standard text models. NVIDIA publishes BF16, FP8, and NVFP4 variants.
