The proposed mechanism leverages cascading sub-cache buffers to selectively retain the most relevant tokens, enabling large language models (LLMs) to maintain longer context histories without increasing cache size. This approach outperforms linear caching baselines across various benchmarks, including streaming perplexity and question answering, while reducing prefill stage latency by a factor of 6.8.

Large language models are great at processing short text sequences, but they struggle with longer texts because it takes too much computer power to keep all the information in memory. To solve this problem, researchers have been working on ways to make these models more efficient. One way is to use a special kind of “cache” that helps the model remember important information without using up too many resources. The new method described in this paper does just that by breaking down the cache into smaller pieces and only keeping the most important information. This makes it possible for large language models to process longer text sequences more quickly, which is important because we need these models to be able to understand and generate text in real-time.
