我其实一直都很赞成AI的快速发展，很少会看到，让我眉头一皱的AI应用场景。 甚至会有点出离了愤怒。 因为可能本心是好的，但是这个方法，却把好心，变成了一个让我非常痛心却又觉得无奈的事件。 这个事情就是，马上毕业季了，很多的学校，为了整治学术不端行为，所以对学生们的论文，除了原来的查重检测之外，引入了AIGC检测。 大概就是用一些所谓的AI检测工具，来检测你的论文里，AI生成的含量有多少。 如果你的AIGC检测比例，如果高于一定的指标，就会无法毕业。 起初我以为这种只是一些造谣的图，在我实际查证之后，我发现，是真的。 已经有多所大学，启动了AIGC检测，并且有明确的指标。 比如4月9日，四川大学教务处发布的《关于开展2025届本科毕业论文（设计）学术不端行为检测工作的通知》中，就明确提到了，20%和15%这两个比 例。 不止一个，还有很多。 如果你去Google上搜一个关键局： 关于2025届本科毕业论文(设计)试行AIGC检测的通知。 你就能看到，大概有哪些学校，在开始实行AIGC检测了。 你如果去小红书在看看，搜索关键词：AIGC论文。 能搜到一大堆的吐槽贴，还有掺杂在里面想捞一笔的所谓几款钱降重的广告。 ...
