Study: long context does not replace retrieval for large corpora

  • Stuffing more documents into a long window still suffers lost-in-the-middle degradation.
  • Selective retrieval with reranking beat naive long-context stuffing on grounded QA.
  • Cost scaled roughly with context length, eroding the convenience argument.

Why it matters. Reinforces a core RAG lesson: a bigger window is a budget, not a dumping ground. Curate and rerank rather than paste everything.

Quick check: What is the most likely cause of mid-document accuracy loss when stuffing a long window?
  1. Correct: Lost-in-the-middle: models attend most to the start and end
  2. The tokenizer corrupts the middle tokens
  3. A hard context limit truncates the middle
  4. Reranking always removes the middle

Position bias means key facts buried mid-context are under-attended; rerank to place them at the edges.
