New speculative decoding method optimizes Mixture-of-Experts models

Researchers have developed a new method for speculative decoding in Mixture-of-Experts (MoE) models, focusing on optimizing expert byte requests and kernel bandwidth. Their approach aims to reduce the computational cost by deduplicating expert calls within a single verification pass, rather than processing each token individually. The study derives theoretical conditions under which this deduplication is faster than standard decoding and provides empirical validation on models like DeepSeek-V2-Lite using frameworks such as CUDA and Metal.
