The full wording of the ruling follows: The GRAMMY Award recognizes creative excellence. Only human creators are eligible to be submitted for consideration for, nominated for, or win a GRAMMY Award. A work that contains no human authorship is not eligible in any Categories. A work that features elements of A.I. material (i.e., material generated by the use of artificial intelligence technology) is eligible in applicable Categories; however: (1) the human authorship component of the work submitted must be meaningful and more than de minimis; (2) such human authorship component must be relevant to the Category in which such work is entered (e.g., if the work is submitted in a songwriting Category, there must be meaningful and more than de minimis human authorship in respect of the music and/or lyrics; if the work is submitted in a performance Category, there must be meaningful and more than de minimis human authorship in respect of the performance); and (3) the author(s) of any A.I. material incorporated into the work are not eligible to be nominees or GRAMMY recipients insofar as their contribution to the portion of the work that consists of such A.I material is concerned. De minimis is defined as lacking significance or importance; so minor as to merit disregard.

the human portion of the of the composition, or the performance, is the only portion that can be awarded or considered for a Grammy Award. So if an AI modeling system or app built a track — ‘wrote’ lyrics and a melody — that would not be eligible for a composition award. But if a human writes a track and AI is used to voice-model, or create a new voice, or use somebody else’s voice, the performance would not be eligible, but the writing of the track and the lyric or top line would be absolutely eligible for an award.”
