Anthropic said future Claude models will weave a hidden marker into the text they generate and attach signed origin data to generated files, so the output can be traced back to the model. The company cited the EU's AI Act as the reason, but said the marking will apply worldwide and across the Claude apps, the developer interface, Claude Code and its cloud partners. Anthropic acknowledged that finding a mark does not prove Claude wrote something, and that its absence does not prove AI was not involved.

What changed

Claude output carried no embedded marker identifying it as machine-generated.

What it unlocks

Recipients of Claude text or files may be able to check whether the content came from an Anthropic model, once detection documentation is published.

What you need to act on it
