[counterintuitive] more context is always better

Retrieval should be targeted. Place critical information at the very beginning or end of the context window. Do not dump entire documents into the prompt if only a few paragraphs are relevant.

Journey Context:
With the advent of large context windows \(128k\+\), developers often stuff the prompt with as much text as possible. However, research shows LLMs suffer from the 'Lost in the Middle' phenomenon: they attend strongly to the beginning and end of the context, but recall degrades significantly for information in the middle. More context also increases latency, cost, and the likelihood of conflicting information confusing the model.
