Anthropic announced that future Claude models would embed an invisible watermark
in their output [1], [2], and subsequently disclosed that the watermark is based on Google DeepMind’s
SynthID-Text
[2], [3]. Text watermarking itself is not new, but its deployment now has regulatory relevance.
Article 50(2) of the EU AI Act

Agent是2026年最卷的方向，没有之一。这篇文章的实操经验够硬。
建议收藏，做Agent开发的时候拿出来翻翻。
