Overview

• Introduces Native Sparse Attention (NSA), a new approach to make transformer attention more efficient
• Challenges current sparse attention methods that claim efficiency gains
• Proposes hardware-aligned sparsity patterns for real performance improvements
• Demonstrates trainable sparse attention patterns without preprocessing
• Shows comparable accuracy to dense attention while using fewer resources

Plain English Explanation

Think of transformer attention like a secretary trying to organize relationships between all items in a massive filing system. Current methods claim to make this faster by only looking at some connections, but they often spend more time figuring out which connections to skip th...
