CoSA: Accelerating Long-Context Inference via Proxy-Kernel Co-Designed Sparse Attention

Yufei Xue, Lin Niu, Hong Liu +6

CoSA introduces a training-free, two-stage sparse attention method that jointly designs a proxy and kernel to efficiently handle very long contexts, achieving faster inference with…
