Researchers at Nous Research have developed Lighthouse Attention, a novel hierarchical attention mechanism designed to accelerate the pretraining of large language models with long contexts. This method achieves a 1.4x to 1.7x speedup compared to standard FlashAttention by pooling queries, keys, and values symmetrically across a multi-level pyramid. Lighthouse Attention places the selection logic outside the attention kernel, allowing it to leverage optimized dense-attention kernels for improved efficiency during training. AI
