What happened
Anthropic will watermark all text and files generated by models released after August 2, 2026, to comply with the EU AI Act's Transparency Code. The watermark travels with copy-pasted text and may persist through some editing, though Anthropic hasn't clarified how much editing removes it. Watermarking applies across Claude API, Claude, Claude Code, Claude Cowork, and Claude Tag, with file watermarking using the C2PA open standard.
Why it matters
If you ship Claude-generated text to end users—especially EU customers—your output will now carry an embedded watermark that survives copy-paste and some editing. Builders using Claude Code or the API should test whether watermarks affect downstream processing, content pipelines, or user-facing output, and factor this into compliance posture for EU markets.
Discussion angle
How robust is the watermark in practice—does it survive enough editing to matter for real workflows, and does it create any risk of false positives or broken formatting in pipelines that consume Claude output programmatically?
