우리는 혼합 전문가(Mixture-of-Experts) 방식의 하이브리드 맘바-트랜스포머(Mamba-Transformer) 언어 모델인 Nemotron 3 Nano 30B-A3B를 소개합니다. Nemotron 3 Nano는 Nemotron 2 대비 3조 개 이상의 새로운 고유 토큰을 포함해 총 25조 개의 텍스트 토큰으로 사전 학습되었으며, 이어서 지도 미세 조정과 다양한 환경에서의 대규모 강화 학습을 수행했습니다. Nemotron 3 Nano는 순전파(forward pass) 시 매번 활성화되는 매개변수가 절반 미만이면서도 이전 세대인 Nemotron 2 Nano보다 더 높은 정확도를 달성합니다. GPT-OSS-20B 및 Qwen3-30B-A3B-Thinking-2507과 같은 유사 규모의 오픈 모델보다 최대 3.3배 높은 추론 처리량을 달성하는 동시에 인기 벤치마크에서도 더 높은 정확도를 보여줍니다. Nemotron 3 Nano는 향상된 에이전트 능력, 추론 능력, 채팅 능력을 입증했으며 최대 100만 토큰의 컨텍스트 길이를 지원합니다. 우리는 사전 학습된 Nemotron 3 Nano 30B-A3B 기본 모델과 사후 학습된 Nemotron 3 Nano 30B-A3B 체크포인트를 Hugging Face에 공개합니다.

English

We present Nemotron 3 Nano 30B-A3B, a Mixture-of-Experts hybrid Mamba-Transformer language model. Nemotron 3 Nano was pretrained on 25 trillion text tokens, including more than 3 trillion new unique tokens over Nemotron 2, followed by supervised fine tuning and large-scale RL on diverse environments. Nemotron 3 Nano achieves better accuracy than our previous generation Nemotron 2 Nano while activating less than half of the parameters per forward pass. It achieves up to 3.3x higher inference throughput than similarly-sized open models like GPT-OSS-20B and Qwen3-30B-A3B-Thinking-2507, while also being more accurate on popular benchmarks. Nemotron 3 Nano demonstrates enhanced agentic, reasoning, and chat abilities and supports context lengths up to 1M tokens. We release both our pretrained Nemotron 3 Nano 30B-A3B Base and post-trained Nemotron 3 Nano 30B-A3B checkpoints on Hugging Face.
