对此，华盛顿大学（UW）SyFI实验室的研究者们提出了一个创新的解决方案：LLMc，即利用大型语言模型自身进行无损文本压缩的引擎。 基准测试结果表明，无论是在维基百科、小说文本还是科学摘要等多种数据集上，LLMc的压缩率都优于传统的压缩工具（如ZIP和LZMA）。同时，与其 他以LLM为基础的闭源压缩系统相比，LLMc也表现出同等甚至更优的性能。 当大语言模型生成海量数据时，数据存储的难题也随之而来。 LLMc并不直接存储词元本身（例如其ID），而是存储该词元在概率排序列表中的"排名"（rank）。这些排名通常是非常小的整数，因此占用的存储空间 极小。 值得一提的是，该项目已经开源，主要作者是来自上海交通大学ACM班的本科生Yi Pan，目前正在华盛顿大学实习。 LLMc的压缩机制 LLMc的灵感来源于实验室一年前的一次内部讨论。当时，研究者们面临一个核心挑战：LLM推理中涉及的内核操作具有高度的非确定性，这使得精确、 可复现的压缩和解压变得困难。 但随着业界在确定性LLM推理方面取得突破，这一问题迎刃而解，也为新引擎的诞生铺平了道路。研究团队顺势快速构建了LLMc的原型，并成功证明用 LLM进行高效压缩的可 ...
