Weaver adapter boosts autoregressive language model speed by 4.37x

Researchers have introduced Weaver, a novel autoregressive adapter designed to enhance the efficiency of speculative decoding in language models. Weaver constructs proposal trees from the top-K marginals of a factorized drafter, restoring conditional dependencies between tokens without requiring a full-vocabulary projection. This approach, combined with optimized CUDA kernels in SGLang for models with Gated Delta Net layers, achieves a 4.37-fold speedup over standard autoregressive decoding and surpasses a DFlash baseline by 24.7%. The work was published on arXiv. AI

IMPACT Improves efficiency of autoregressive language models, potentially leading to faster and more interactive AI applications.
