- TLDR:Simplified Sparse Attention is introduced, a simpler approach to sparse attention that requires no architectural changes that outperforms full attention in retrieval-augmented generation and extends to a hierarchical gist-of-gist variant that achieves log-linear decoding complexity while maintaining or improving accuracy at high compression ratios up to 32x.

- 标题中文:基于 Gist Token 的简化稀疏注意力
- TLDR中文:提出 Simplified Sparse Attention——一种更简洁的稀疏注意力方案,无需任何架构改动,在检索增强生成中优于全注意力;并扩展为分层 gist-of-gist 变体,在高达 32× 的高压缩比下保持或提升精度,同时实现对数级解码复杂度。
