Researchers have introduced two novel attention mechanisms, CoWindow Attention (CoWA) and MassAlloc Attention (MALA), designed to improve computational efficiency in large language models. CoWA distributes attention across multiple KV heads using complementary windows, enabling sparse attention while maintaining full causal coverage. MALA optimizes computation by using attention's softmax statistics to selectively perform post-score calculations. Both methods demonstrate significant speedups in attention operations, with CoWA achieving up to 7.4x faster forward passes and MALA offering a 2.2x speedup, leading to reduced training FLOPs without compromising model capabilities.
