Kimi delta attention is an improvement in the direction of linear attention, replacing explicit caching of the full sequence with incremental state updates, reducing memory complexity from growing with length to nearly constant.

UnverifiedThe KV Cache footprint of linear attention is independent of sequence length, whereas the cache of traditional attention grows linearly with sequence length.77% similarUnverifiedThe recursive state-compression structure of linear attention brings constant memory usage and linear time, but all historical information must be squeezed into a fixed-size memory, and interference easily occurs when new information conflicts with old information.73% similarUnverifiedHSTU uses a linear-complexity attention variant, so processing behavior sequences longer than several thousand does not result in quadratic growth in computational cost.70% similarVerifiedMemory retrieval should layer in time decay, importance weighting, and hybrid retrieval, rather than relying solely on vector similarity.70% similarUnverified在推理阶段内存带宽往往比纯算力更早成为瓶颈，注意力机制需在每步生成时读取全部KV缓存，上下文长度增大时内存读写开销呈平方级增长69% similar
