喂给 AI 厚 PDF Word Excel?它只看了头尾

喂给 AI 厚 PDF Word Excel？它只看了头尾

⚠️警告：别信大模型通读厚 PDF Word Excel，它其实只读了不到 10%！

研究表明，大模型在阅读超长文本时，对开头和结尾的记忆力最强，而对文本中间部分的内容极易选择性忽略。如果你问的问题恰好隐藏在长文档的第 45% 处，模型很可能会告诉你“文档中没有提到”。

当你问它一个被它省略掉的细节时，大模型很少会老老实实承认：“对不起，由于文件太长，中间那部分我没读。” 相反，它为了顺从你，会根据上下文的蛛丝马迹去盲猜或者编造一个答案。这在处理复杂的财务报表（Excel）或法律合同（PDF）时非常致命。
