text generation

Anthropic announced on August 11 that all future Claude models will embed an invisible watermark in generated text, following Google's lead with SynthID-Text. The move is partly driven by the EU AI Act, which mandates watermarking for AI models released after August 2, 2026, though researchers remain split on whether the technique degrades output quality.

Anthropic has begun embedding invisible watermarks into Claude's generated text so it can later identify AI-authored content. ML educator Sebastian Raschka published a detailed 48-minute video explainer breaking down how the underlying token-sampling mechanism works.
