The paper "Optimizing watermarks for large language models" discusses the growing importance of watermarks for generative LLMs amid concerns about misuse. It presents a systematic multi‑objective optimization framework to balance watermark identifiability with the impact on text quality. The authors identify Pareto‑optimal solutions for a broad class of robust, efficient watermarks that outperform the current default watermark.

arXiv:2606. 18430v1 Announce Type: new Abstract: Statistical watermarks help organizations attribute large language model (LLM) outputs, yet existing detectors often struggle when watermark signals are weak, texts are repetitive, or watermarks are edited.

The paper introduces the first watermark designed specifically for diffusion language models (DLMs), which generate tokens in arbitrary order unlike traditional autoregressive models. It overcomes the challenge of missing prior tokens by applying the watermark in expectation over the context and promoting tokens that strengthen the watermark when used as context. Experiments show a >99% true positive rate with minimal quality loss and comparable robustness to existing autoregressive watermarks.
