DECO: Sparse Mixture-of-Experts with Dense-Comparable Performance on End-Side Devices

arXiv:2605.10933v3 Announce Type: replace Abstract: While Mixture-of-Experts (MoE) scales model capacity without proportionally increasing computation, its massive total parameter footprint creates significant storage and memory-access bottlenecks, which hinder efficient end-side deployment that simultaneously requires high performance, low computational cost, and small storage overhead. To achieve these properties, we present DECO, a sparse MoE architecture designed to match the performance of dense Transformers under identical total parameter budgets and training tokens. DECO utilizes the di

Why this matters
Why now

The rapid advancement of AI models necessitates solutions for deploying increasingly complex architectures efficiently on resource-constrained 'end-side' devices.

Why it’s important
