Anthropic 推出不可见 AI 文本水印以遵守欧盟人工智能法案
作者PulseAugur 编辑部·[105 个来源]·
Anthropic 已开始在其 Claude 模型中实施不可见水印，以识别 AI 生成的文本和图像，从而遵守欧盟人工智能法案。这项技术与 Scott Aaronson 等研究人员合作开发，在模型的标记选择中嵌入细微的模式，使其能够通过特定密钥检测到，而不会影响输出质量。虽然 Google 已为 Gemini 使用了类似的系统，OpenAI 也计划效仿，但这些水印的有效性仍存在争议，已有工具出现可以去除它们，这引发了关于归属和 AI 内容识别未来的问题。

arXiv:2506.22343v2 Announce Type: replace-cross Abstract: Text watermarks in large language models (LLMs) are an increasingly important tool for detecting synthetic text and distinguishing human-written content from LLM-generated text. While most existing studies focus on determi…

More AI models will be adding watermarks soon (like SynthID). I guess partially due to the EU AI act. But I was thinking, might it be to prevent the AI models from eating their digital poo as input? # AI # DAIrrhea
