WaterMax: breaking the LLM watermark detectability-robustness-quality trade-off

Understand

Watermarking is a technical means to dissuade malfeasant usage of Large Language Models.

• This paper proposes a novel watermarking scheme, so-called WaterMax, that enjoys high detectability while sustaining the quality of the generated text of the original LLM.
• Its new design leaves the LLM untouched (no modification of the weights, logits, temperature, or sampling technique).
• WaterMax balances robustness and complexity contrary to the watermarking techniques of the literature inherently provoking a trade-off between quality and robustness.
