Large Reasoning Models (LRMs) excel on complex tasks through long chain-of-thought (CoT) reasoning, but their lengthy intermediate steps cause severe overthinking that inflates inference cost. KV-cache compression is a common solution, yet existing reasoning-oriented methods apply a uniform policy across the trajectory and judge compression only by what it removes from the cache.

GrowPage is an on‑demand key–value (KV) budgeting framework designed to improve large language model (LLM) reasoning serving. It treats KV capacity as a runtime resource, using lightweight dual‑timescale query summaries to track recent and long‑term attention patterns and estimate demand evolution. At each capacity boundary, GrowPage either compresses KV states within the current allocation or acquires an additional physical page, integrating with PagedAttention’s page‑level memory abstraction to maintain continuous batching and prefix caching.
