Nemotron 3 Nano 30B A3B

nvidia/nemotron-3-nano-30b-a3b
Nemotron-3-Nano-30B-A3B is NVIDIA's compute-efficient, open-weight reasoning model built for agentic AI. Its Mixture-of-Experts design (30B total / 3.5B active) with a hybrid Mamba-2 + Transformer architecture delivers strong reasoning and tool use at a fraction of the compute required by comparable dense models. It supports a 256K context window, toggleable chain-of-thought reasoning, function calling, and structured (JSON) outputs — making it well-suited for long-context agents, coding, and math. Released under the NVIDIA Nemotron Open Model License and ready for commercial use.
