arXiv:2605.00768v3 Announce Type: replace Abstract: The transformer is the most popular neural architecture for language modeling. The cornerstone of the transformer is its global attention mechanism, which lets the model aggregate information from all preceding tokens before generating the next token. One common variant of attention is called local attention, which restricts each token to aggregating information from a bounded window of predecessors, reducing the quadratic cost of global attention to linear. Although this restriction is usually motivated by efficiency, it has also been found
Ongoing research into transformer architectures continues to seek more efficient and scalable models, with local attention being a key area of investigation for balancing performance and computational cost.
Understanding the expressivity limits of local attention informs the design of more efficient and powerful large language models, impacting the future trajectory of AI development and its deployment costs.
The theoretical understanding of local attention's capabilities and limitations is refined, potentially guiding future architectural choices in AI research and commercial systems towards more resource-efficient designs.
