Why is Speculative Decoding Fast? (4 minute read)

TLDR AI ↗ · 2026-10-09 Cached

一篇技术博客深入解释了投机解码为什么快:并非因为总FLOPs减少(实际上反而增加),而是因为它改变了GPU的工作类型——在低批量场景下把原本空闲的算力从内存瓶颈(memory-bound)转为计算瓶颈(compute-bound),用单序列的'深度'换取了批量解码的'广度'。

KVFetch: Temporal Prefetching for the Missing Half of KV Cache Compression

arXiv cs.LG ↗ · 2026-10-08 Cached

The paper introduces KVFetch, a training-free framework that adds a temporal recall channel to score-based KV cache compressors to fix "sequential forgetting" (verbatim copying breaking under compression), recovering copying performance from 0.8 to 78.4 and boosting the RULER-16K average by +8.4 at iso-budget.

Cache the Encoder Within:Compact, Reusable Memory across LLM Queries

arXiv cs.CL ↗ · 2026-10-08 Cached

EncBank extends CoMem's intermediate-state interface, treating an LLM's lower layers as a reusable document encoder whose compact low-bit outputs can be cached and reused across queries. Evaluated on Qwen backbones, 4-bit storage nearly matches native precision while cutting persistent storage to 28.1%, with notable prefill speedups at some accuracy cost.
