Researchers have developed a new method called REAL (REtrieval-reAsoning and Logic-constructed) to compress key-value (KV) caches for large language models, addressing challenges posed by increasing sequence lengths. Unlike previous methods that focused only on successful retrieval cases, REAL analyzes attention head behaviors in both success and failure scenarios. By strengthening valid reasoning pathways and inhibiting noise from bias and distraction, REAL achieves comparable accuracy to existing methods while requiring significantly less space, demonstrated by a 32x reduction on the LongBench v2 benchmark.
