arXiv:2606.13126v1 Announce Type: cross Abstract: Retrieval-augmented and agentic workloads repeatedly prefill recurring predictable structured inputs (which we call "spans") such as documents and code files. Yet, prefix caching in engines such as vLLM cannot reuse their KV entries unless they share identical prefixes with another request, while Position-Independent Caching (PIC) implementations within production-grade inference servers typically either require substantial server code changes or keep KV state outside the server, incurring host-to-device transfer overhead. We present Minimalist
The increasing complexity and scale of AI models, particularly in retrieval-augmented and agentic contexts, are driving an urgent need for more efficient memory and caching solutions.
Improved caching mechanisms like MiniPIC can significantly reduce the computational cost and latency of large language models, making AI applications more scalable and economically viable.
The ability to reuse KV entries more flexibly, irrespective of prefix identity, changes the economics of inference for recurring structured AI workloads, potentially lowering operational expenses significantly.
