[counterintuitive] more context window usage improves accuracy

Place the most critical information at the very beginning or end of the context window. Filter and rank retrieved context aggressively rather than stuffing the prompt.

Journey Context:
Developers assume that since models have large context windows \(128k\+\), they should stuff as much relevant data as possible into the prompt. However, research shows LLMs suffer from 'Lost in the Middle' degradation: they recall information at the beginning and end of the context very well, but accuracy drops significantly for information in the middle. More context also increases latency, cost, and the chance of conflicting information.
