Abstract

RBS-Attention introduces a training-free sparse-prefill method that enhances long-context large language model inference by addressing mean dilution through dual-branch selection.

Reality Card

Core Claim

RBS-Attention achieves up to 20.65× standalone prefill-attention speedup on H100 GPUs while maintaining high accuracy.

Method / Result

20.65× standalone prefill-attention speedup

Limitations

The paper does not provide detailed information on the reproducibility of the results or the specific implementation details.
