Are there any cases where AI training was "fair use"?

Question

Are there any cases in the world about this (including with local equivalents of "fair use" law)?

Answer 1

As always, fair use is decided case-by-case, and depends on the particular use to which the copy is put. "Training AI" is not specific enough to analyze for fair use. Some copying to train AI will be fair use; some will not.

But one example where copying to train AI was found to be fair use is Authors Guild v. Google. In that circumstance, it was fair use to copy books to train a search AI.
