Older Claude text watermarks can be bypassed by changing sampling parameters
1 report1 sourceupdated 3 hours ago
What happened
AI digest
On November 5, The Decoder reported that text watermarks on several older Claude models only hold under default sampling parameters. Changing any one of temperature, top_p or top_k bypasses the watermark on those older models, the report said. It ties the bypass to sampling parameter changes and covers several older Claude models. It gives no specific model versions or test details, and does not say whether newer Claude models behave the same way or whether Anthropic has responded.
