AI licensing for authors: Who owns the rights, and what’s the split?

The Authors Guild recently published a statement asserting that standard book publishing agreements do not grant publishers AI training rights; those rights remain with the author. (So far, Big Five publishers have proceeded as if they agree on this.) That means publishers must secure author permission to sell AI training rights under standard publishing agreements. The Authors Guild suggests a 75–85 percent split in favor of the author is fair.
