Anthropic has begun embedding invisible watermarks into text generated by its Claude AI model, a change prompted by the EU Code of Practice on Transparency of AI-Generated Content. This technique, based on Google DeepMind's SynthID-Text, subtly alters word choices that appear random to readers but can be detected with a key. While the watermark is designed to survive minor edits like grammar checks, it can be removed by substantial rewrites. Anthropic plans to release a detection API, which will allow for the verification of content originating from Claude. AI
