arXiv:2607.05694v1 Announce Type: cross Abstract: Logit-based watermarking is a widely used mechanism for identifying LLM generated content, yet its effectiveness is governed by a fundamental trade-off between detectability and semantic distortion. Existing analyses provide limited guidance for principled hyperparameter selection, leaving practical deployments reliant on heuristic tuning. In this work, we develop a power-calibrated statistical framework that establishes explicit quantitative relationships between watermark hyperparameters, detection power, and distortion. This characterization
The proliferation of LLMs and the increasing need to distinguish between human and AI-generated content necessitates more robust and quantifiable watermarking methods, moving beyond ad-hoc solutions.
This work provides a critical advancement in LLM watermarking, enabling more reliable content provenance and mitigating risks associated with untraceable AI-generated text, which has implications for misinformation, intellectual property, and cybersecurity.
The ability to scientifically calibrate LLM watermarks shifts their deployment from heuristic guesswork to a principled engineering task, offering clearer trade-offs between detection strength and content quality.

Improved detection capabilities for AI-generated text will enhance trust in digital content.
This framework could influence future AI regulations regarding content attribution and responsibility.
More robust watermarking might accelerate the adoption of AI in sensitive applications where content provenance is paramount, yet could also incentivize more sophisticated adversarial attacks.
