Peer reviewers play a vital role in scientific publishing. Their expert evaluations and recommendations guide editors' decisions and ensure that published research is valid, rigorous, and credible. Editors select peer reviewers primarily because of their in-depth knowledge of the subject matter or methods of the work they are asked to evaluate. This expertise is invaluable and irreplaceable. Peer reviewers are accountable for the accuracy and views expressed in their reports, and the peer review process operates on a principle of mutual trust between authors, reviewers, and editors. Despite rapid progress, generative AI tools have considerable limitations: they can lack up-to-date knowledge and may produce nonsensical, biased, or false information. Manuscripts may also include sensitive or proprietary information that should not be shared outside the peer review process.
If any part of the evaluation of the claims made in the manuscript was supported by an AI tool, we ask peer reviewers to declare the use of such tools transparently in the peer review report.
