  "title": "MetaKV: Adaptive KV Cache Compression for Constrained LLM Inference",
  "summary": "MetaKV replaces a single fixed KV cache compression configuration with per-prompt selection among existing methods (KVQuant, H2O, RocketKV, FP16) guided by lightweight predictors of latency, peak memory, and correctness. The cost is training and maintaining three prediction models plus a selection step per prompt, adding engineering complexity and a small inference-time overhead on top of the underlying compressors. It can fail if the accuracy or latency predictors mispredict on out-of-distribution prompts or on hardware and models different from the evaluation setup, causing constraint violations or suboptimal choices.",
  "rationale": "The framework sits on top of compression methods the reader can already run on a 24 GB GPU, but its benefit depends on predictor accuracy for the reader's specific model, hardware, and workload, so it warrants a small-scale validation before production adoption.",
