An AI development team is building a model to summarize entire books, which involves processing extremely long sequences of text. To manage the computational resources, they decide to replace the standard self-attention mechanism, where every token attends to every other token, with a sparse one that restricts connections. Which of the following statements provides the most accurate evaluation of this decision's primary trade-off?

A large language model processes a long document. Consider two different sparse attention patterns that could be used instead of the standard all-to-all attention:

• Pattern A: Each token can only attend to the 16 tokens immediately preceding and following it.
• Pattern B: In addition to its local neighbors, each token can also attend to a few pre-selected 'global' tokens that are distributed across the entire sequence (e.g., the first token, the last token).
