KVShareArena: KV-Cache Reuse Across Contexts and Model Checkpoints

A new arXiv paper tackles a limitation in LLM serving systems, which typically reuse KV caches only when shared text appears at the very start of a prompt. The authors target two workloads that break this rule: retrieval-augmented generation servers that assemble different retrieved chunks per request, and requests served across different model checkpoints. KVShareArena aims to expand cache reuse in these cases, reducing redundant computation and improving serving efficiency.
