Chunked and Windowed Attention
Chunked and windowed attention is a technique designed to mitigate the memory consumption of the KV cache. It works by limiting the self-attention mechanism's scope to a recent subset of tokens (a 'window' or 'chunk'). This approach effectively reduces the size of the KV cache that needs to be stored. However, this memory saving comes with a trade-off: it can lead to a loss of context from older tokens or require additional computation to reprocess past information if needed.

Chunked and Windowed Attention
An engineer is deploying a large language model for a task that requires processing very long sequences of text. During testing, they observe that the system's memory usage grows linearly with the length of the input sequence, eventually causing the system to run out of memory and fail. Which of the following strategies correctly identifies the underlying trade-off to mitigate this specific memory issue?

Learn After
A developer is designing a language model for summarizing very long legal documents, where details mentioned at the beginning can be crucial for the overall summary. To manage memory usage on a constrained hardware setup, the developer implements a self-attention mechanism that, for each new token, only considers the preceding 1024 tokens. What is the most significant trade-off for this specific application?
