The authors compared factual accuracy of watermarked versus unwatermarked outputs from large language models in a controlled retrieval-augmented generation (RAG) setting.
Watermarking LLM outputs can induce factual errors even with correct context
A controlled study across six watermarking methods shows that text provenance signals systematically reduce factual accuracy, and the authors propose two interventions that cut errors by 90%.

In one line
Text watermarking can induce factual errors in otherwise correct, context-grounded LLM answers, while token and attention interventions reduce those errors by about 90%.
