OpenAI 在 ChatGPT 和 Codex 中加入文本水印
OpenAI is adding text watermarking in ChatGPT and Codex
OpenAI 正在为 ChatGPT 和 Codex 的文本输出加入不可见、机器可读的水印，首批仅面向欧盟用户。OpenAI 称其 textGrain 水印在效果上匹配或超过 Google DeepMind 的 SynthID 等方案，并给出基准测试显示加水印与未加水印文本性能相近。OpenAI 同时说明 textGrain 不保证可靠检测，文本水印也无法验证准确性、确定文本归属、衡量人类贡献比例或证明人类作者身份。

An invisible, machine-readable watermark in text output is rolling out to ChatGPT and Codex, but only for users in the European Union at first.
OpenAI says its textGrain watermarking “matched or exceeded” other approaches like Google DeepMind’s SynthID for text, which is also the basis for the watermarking Anthropic announced in August . Like OpenAI, Anthropic made the move to meet the requirements of the EU’s AI Act ; however, not everyone was happy to learn about the addition.
OpenAI also included scores from AI benchmarks showing similar performance from watermarked and unwatermarked text. But it notes that textGrain “does not guarantee reliable detection,” and says text watermarks don’t verify accuracy, determine who owns the text, measure how much a human contributed, or prove human authorship.
