NVIDIA unveils efficient Nemotron 3 LLM family with hybrid architecture

By PulseAugur Editorial · [1 sources] ·

NVIDIA has released two new large language models, Nemotron 3 Nano and Nemotron 3 Ultra, focusing on efficiency and advanced capabilities. Nemotron 3 Nano is a 30B-class model designed for private inference and agentic workflows, featuring a hybrid Mamba-Transformer Mixture-of-Experts architecture and supporting up to 1 million tokens for long-context applications. Nemotron 3 Ultra, a 550B-parameter model, utilizes a similar hybrid architecture with LatentMoE to achieve faster inference speeds than similarly sized models, incorporating native speculative decoding and trained with a novel 4-bit precision format.
