Researchers have developed IndexCache, a method to optimize DeepSeek Sparse Attention (DSA) by reducing redundant computations in large language models. The core idea is that adjacent layers in a model often select the same important tokens, making the indexer's work in each layer largely redundant. IndexCache designates certain layers as 'Full' (F) to compute and cache token selections, while 'Shared' (S) layers reuse these cached selections, significantly cutting down on computation without altering the model's architecture.
