OpenAI 将在欧盟为 ChatGPT 和 Codex 输出嵌入不可见文本水印
OpenAI 要在欧盟给 ChatGPT 和 Codex 输出加文字水印了，不过换个 25% 的同义词就能把检测率从 92% 打到 17%，先看看再担心。
OpenAI 宣布未来几周内在欧盟为 ChatGPT 和 Codex 的输出添加嵌入措辞本身的不可见文本水印，以响应《欧盟 AI 法案》的检测要求。OpenAI 称测试显示质量没有明显损失。但一项针对 400-token 段落的测试显示，把 25% 的词替换成同义词后，水印检测率从约 92% 降到 17%。水印也无法区分人类贡献了多少，自己写、让 ChatGPT 修改过的文本同样可能带上水印。
OpenAI will start changing ChatGPT’s word choices in the EU to make its text detectable, and I don’t like this direction.
Over the coming weeks, ChatGPT and Codex outputs will receive invisible text watermarks in response to the EU AI Act. The pattern is embedded in the wording itself.
OpenAI says its tests show no meaningful quality loss. Still, I’m dislike with detection requirements influencing how a writing tool phrases my text.
Especially given the limitations: in one test on 400-token passages, replacing 25% of words with synonyms cut watermark detection from about 92% to 17%.
The watermark also cannot distinguish how much a human contributed. Even text you wrote yourself and had ChatGPT edit can carry it.
The EU is once again concerning itself with the really important things (sarcasm).
