The Wall Street Journal reported that the new Sora can make videos that include copyright material unless copyright holders specifically opt out of allowing their works to appear. Mark Lemley, a professor at Stanford Law School, said, “I think they are certainly opening themselves up to lawsuits in particular cases,” warning about copyright issues.

Lemley’s warning came after pointing out Anthropic’s case, where the AI company had to pay at least $1.5 billion to settle a copyright infringement lawsuit because it used pirated books to train its language models. The Wall Street Journal’s parent company, News Corp, has a content deal with OpenAI.
