Yes, as announced in a June 23, 2023 Guide notice, NIH prohibits peer reviewers from using natural language processors, large language models, or other generative artificial intelligence (AI) technologies for analyzing and formulating peer review critiques for grant applications and contract proposals.
NIH set this rule because of confidentiality concerns—inputting substantial, detailed information into a generative AI tool forfeits control of where that data may be sent, saved, viewed, or used in the future. Exemptions exist only for computer technologies serving accessibility needs.
Read the Open Mike blog post Using AI in Peer Review Is a Breach of Confidentiality for a longer discussion of the policy decision, which includes a nod to NIH’s stance on using AI to write a grant application (spoiler alert: there are issues with plagiarism).
