From their rules:
GENERATIVE ARTIFICIAL INTELLIGENCE
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.
