标题为英语RBS-Attention: Radius-Bounded Sparse Prefill for Long-Context Large Language Models

Long-context large language model inference is increasingly limited by prefill, where dense self-attention processes the entire prompt before generation begins. Sparse block selection can reduce this cost, but a block centroid may hide a highly relevant token among many…
