I don’t get that, the use of these books was instrumental and necessary for the success of the training run. The expected value of these training runs is high as the build out of 100 billion+ infrastructure demonstrates, so the book publishers should at a minimum be paid a licensing fee, a small fraction of every inference run revenue or whatever they decide. The fact that authors and publishers didn’t get any say under what conditions their intellectual property can be used is pretty outrageous.

The conclusion was they suffered no legal harm, in that their interests such as their continued publishing of books was not affected by LLMs; no one is using AI to compete with publishers, if anything "authors" might very well use those same publishers to get their generated books on shelves.

If it's fair use, no licensing fee is needed.
