Can we Watermark Low-Entropy LLM Outputs?

Researchers have developed new watermarking techniques for large language model outputs that do not alter the output distribution but can identify the source LLM, even when adversaries attempt to edit the content. This matters because it enhances security by making watermarks harder to remove or tamper with, especially in scenarios where token entropy is low and alphabet size constraints are relaxed. Developers should watch for further advancements in practical implementations of these schemes.
