Nemotron 3 Nano's new step beyond Nemotron Nano 2 9B is a sparse mixture-of-experts design. The 30-billion-parameter checkpoint activates 3.5 billion parameters per token and combines Mamba2, Transformer, and attention. Reasoning and an explicit thinking budget make the planning share configurable.

NVIDIA lists up to 1M context tokens, six supported languages, and coding with tool use. The open weights are intended for custom inference. The 3.5 billion active parameters describe the per-token activation, not the checkpoint's total memory requirement.
