Anthropic has done something disgusting again.

Starting from August 2, all Claude output text will include invisible watermarks.

This text watermark is different from the image watermarks we usually understand. It is not hidden characters embedded in the image or text, but is directly contained in the text output itself.

The large language models we use today are essentially a matter of random probability.

For example, when asking the model to describe the weather, it might output “gloomy” or “gray and overcast.” Either one makes sense; the choice depends on an internal random number.

The hidden watermark manipulates this random number.

Anthropic uses a key known only to itself to tinker with the dice in these originally luck-based positions, secretly increasing the probability of certain groups of words appearing.
