The new preprint server allows the submission of articles that have been written in whole or in part by artificial intelligence (AI) and also accepts reviews created by AI[?]. The server was introduced in an article in Science (Volume 390, Issue 6779, pages 1202-1203, December 2025)[?] According to the article, the server accepts manuscripts where authors have used generative models to generate the text or to perform the review, as long as it is consistent with the server's rules[?]. The article describes that server operators have implemented specific requirements for indicating the use of AI in submissions and reviews, including the obligation to indicate which parts of the text or review were generated by AI[?] The text states that the server aims to enable rapid sharing of results, including materials created or reviewed by AI, to identify their benefits and limitations in academic communication[?] The article also outlines the concerns and debate in the scientific community about trust and accountability when using AI for writing and peer review, including issues of transparency and verifiability of content[?] The author(s) of Science provides examples or comments from experts on the need for rules for labeling AI contributions and on the potential risks of improper or unlabeled use of AI in publishing[?] Specific server rules and reactions from members of the scientific community are cited in the text; the article does not present new empirical data from the study, but reports on the launch of the service and the reactions associated with its rules[?]
