OpenAI文本水印textGrain或难满足欧盟合规要求
Start here
测试显示，OpenAI针对欧盟《人工智能法案》透明度规则开发的文本水印技术textGrain，在短文本和二次编辑场景下检测率显著下降，可能难以满足监管合规要求。测试数据显示，约150词的文本中该水印检出率为80%，但在替换25%的同义词后，检出率骤降至17%。欧盟相关法案明确规定合成内容必须具备鲁棒可靠的机读标识，研究人员指出该技术目前尚缺乏独立验证，若最终被监管部门判定违规，可能面临高额罚款。

- Hacker News · AISelectedAI Text Watermarking May Struggle to Meet New EU Transparency Regulations
Tests show that textGrain, a text-watermarking technique developed by OpenAI to comply with EU AI Act transparency rules, suffers a sharp drop in detection rates for short texts and post-edited content, potentially falling short of compliance requirements. In tests, the detection rate reached 80% for passages of around 150 words, but plunged to 17% when 25% of the words were replaced with synonyms. The EU AI Act mandates robust, machine-readable markings for synthetic content; researchers note the method still lacks independent validation and could expose companies to heavy fines if found non-compliant.
