Overview

• Q-Filters compress key-value caches in large language models by 60-80%
• Uses geometry of query-key attention patterns to predict important keys
• Operates on a per-head basis to maximize compression effectiveness
• Achieves near-zero performance loss while significantly reducing memory
• Outperforms other compression methods in speed-memory-quality tradeoffs

Plain English Explanation

Large language models like GPT-4 need enormous amounts of memory to function. When generating text, these models store information in what's called a "key-value cache" to avoid repeating calculations. This cache grows larger with each new word generated, creating a memory bottl...
