長上下文忠實度衰退

Operation & Monitoring

Risk Description

LLM faithfulness to input significantly degrades for information in middle positions of long contexts (the "lost in the middle" phenomenon). Models tend to over-rely on information at the beginning and end of context while ignoring or distorting key content in the middle. In document summarization, contract review, or long-form analysis, this may cause critical clauses and data to be missed or misrepresented.

Implementation Steps English translation pending

  1. 對長文件採用分段處理再彙整的策略,避免單一超長輸入
  2. 將最關鍵的資訊放置在上下文的開頭或結尾位置
  3. 實施輸出完整性檢查,比對摘要是否涵蓋所有文件章節
  4. 在關鍵場景中使用多次查詢交叉驗證,確保全面覆蓋
