Compactor: Calibrated Query-Agnostic KV Cache Compression with Approximate Leverage Scores

arXiv — cs.CLWednesday, December 10, 2025 at 5:00:00 AM
  • Compactor has been introduced as a training-free, query-agnostic key-value (KV) cache compression strategy for large language models (LLMs), utilizing approximate leverage scores to assess token importance. This method allows for a reduction of 20% in token retention while maintaining performance across various tasks, achieving a 68% reduction in KV memory burden on average.
  • This development is significant as it enhances the efficiency of LLMs, making them more robust in handling extensive contexts without sacrificing performance, which is crucial for applications requiring large context windows.
  • The introduction of Compactor reflects a growing trend in the AI field towards optimizing memory usage and processing efficiency in LLMs. This aligns with other emerging frameworks that address similar challenges, indicating a concerted effort within the industry to improve the scalability and performance of AI models in real-world applications.
