Anthropic has implemented invisible watermarks in its Claude AI model outputs to comply with the EU AI Act, which mandates synthetic content labeling with fines up to 3% of global turnover for non-compliance. The watermarking technique is based on Google's SynthID and covers text and image outputs, though removal tools have emerged rapidly, highlighting ongoing technical challenges.

◆ ◆ The Wire takeaway
You must embed reliable content identification if you deploy AI in Europe or serve European users, or face a costly regulatory penalty. Anthropic’s public watermark rollout forces you to treat AI transparency as a market requirement, not a future feature.
