NVIDIA Explains Dense vs MoE Architectures Using Nemotron 3.5 Lightning
NVIDIA published a developer blog comparing dense and Mixture-of-Experts (MoE) model architectures. It uses Nemotron 3.5 Lightning as an example: a 30B-parameter MoE model that activates only 3B parameters per token by selecting a subset of experts, while retaining the capacity of the larger model. The post covers active parameters, throughput, and selection guidance.
