Researchers have developed GraniKV, a novel KV-cache layer designed to optimize serving engines for multi-agent systems with long shared prefixes. This system employs asymmetric paging granularity, allocating the shared prefix contiguously and the per-request suffix with fine-grained allocation. GraniKV integrates cascade attention and a dispatcher that selects optimal backends based on workload demands. The system demonstrated significant throughput gains, reaching up to 2.16x over a production baseline on models like Llama-3.1-8B and Qwen-2.5 series. AI
