English(EN) Reading Vertically: PHOTON and the KV-Cache Bottleneck

PHOTON 架构通过垂直读取解决 KV 缓存瓶颈

一种名为 PHOTON 的新 AI 架构被提出,用于解决语言模型中的 KV 缓存瓶颈。与传统 Transformer 模型水平读取上下文并在每个新 token 时重新读取整个内存不同,PHOTON 采用垂直读取方式。它将 token 压缩成粗略摘要,显著减少了需要重新读取的数据量,从而加快文本生成速度,尤其是在长上下文场景下。该架构由一个分块器、一个转换器和一个局部解码器组成,其关键创新在于一个固定大小的局部重建窗口,该窗口不会随着上下文长度的增加而增长。 AI

影响 这种新架构通过降低内存带宽需求,有望显著提高 LLM 的效率,尤其是在长上下文生成方面。
