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

Explain Like I'm Normal

Researchers have developed GrowPage, a framework that dynamically adjusts KV cache memory budgets during inference rather than using a fixed size. By tracking 'dual-timescale' attention summaries, the system allocates memory only when a reasoning chain actually needs it, significantly lowering the hardware requirements for long-context LLM serving.
