RelaxKV: Recomputation Guided by the Query with Sparse Context Attention for Efficient KV Cache Reuse

Cross-request KV caching reduces the prefill cost of Retrieval-Augmented Generation (RAG), but conventional prefix caching severely limits cache reuse across requests. Position-Independent Caching (PIC) removes this constraint by reusing independent chunks, but their KV states miss cross-chunk interactions. Existing me...

Towards Efficient Serving of Network-intensive LLM Inferences

Prefix caching has become a key technique for LLM serving, and nowadays the reusable KVCache contents are often hosted on distributed servers. For long-context LLM inferences with high cache hit ratio, cross-server KVCache transmission has become an emerging performance bottleneck; such network-intensive LLM inferences...
