- TLDR:This work introduces Grouped Value Attention (GVA), which stores grouped values and reconstructs content keys with a learned linear map at inference, which can be absorbed into the query, eliminating the need to materialize content keys in the intended decode path.

- TLDR中文:该工作提出了分组值注意力(Grouped Value Attention, GVA),通过存储分组值并在推理时利用可学习的线性映射重构内容键,该映射可被吸收进 query 中,从而在预期解码路径中无需显式物化内容键。
