KVDiagnosis: A Diagnostic Benchmark for KV-Cache Compression in Long-Context Language Models

Chen Qiu, Ziwu Liu, Chao Fei +2

KV-cache compression reduces long-context memory, but aggregate task scores reveal neither which correct executions fail nor why. We present KVDiagnosis, a diagnostic dataset and b…

ART: Attention Run-time Termination for Efficient Large Language Model Decoding

Chen Qiu, Guozhong Li, Cristian McGee +2

Long-context decoding in Large Language Models (LLMs) is constrained by the cost of accessing and processing the Key-Value (KV) cache. Despite evidence that attention outputs depen…

CHESS: Context-aware Hierarchical Efficient Semantic Selection for Long-Context LLM Inference

Chao Fei, Guozhong Li, Chenxi Liu +1

Long-context LLMs demand accurate inference at low latency, yet decoding becomes primarily constrained by KV cache as context grows. Prior pruning methods are largely context-agnos…
