Researchers have introduced Kwai Summary Attention (KSA), a novel attention mechanism designed to address the quadratic time complexity of standard softmax attention in large language models. KSA aims to maintain a linear relationship between the KV cache and sequence length by compressing historical contexts into learnable summary tokens. This approach seeks to balance memory costs with effective retention of long-distance dependencies, offering an alternative to existing methods that either reduce KV cache or use KV cache-friendly architectures.
