[counterintuitive] Stuffing the maximum context window improves RAG accuracy

Keep retrieved context concise and place the most critical information at the very beginning or end of the prompt.

Journey Context:
Developers assume 128k context means they can dump 100k tokens of retrieved docs. Research shows LLMs suffer from 'lost in the middle' degradation; they reliably recall info at the start/end of the context but ignore or hallucinate around info in the middle. More context often means more noise and lower accuracy.
