Nemotron 3 Nano 30B A3B

by NVIDIA

Nemotron 3 Nano 30B A3B is the A3B build of NVIDIA's open-weight Nano reasoning model, configured for a 262K token context to handle long documents and multi-turn agentic workflows. The architecture combines Mamba-2 and Transformer layers with Mixture-of-Experts routing, activating roughly 3.5B parameters per token while retaining 30B total capacity. Trained on 25 trillion tokens of diverse data spanning code, math, science, and web content, the model performs well on reasoning, code, and agent-style tasks, and supports structured output for tool-calling and function composition. It covers a handful of natural languages and a wide range of programming languages. The A3B build is aimed at AI agent systems, multi-agent architectures, and high-throughput inference, and is available in BF16 precision for commercial deployment.
