The Wikimedia Foundation filed an amicus brief in copyright litigation involving publishers including The New York Times, OpenAI and Microsoft, arguing against a blanket victory for either side. It distinguishes pretraining that creates new functionality from reproducing material in outputs that substitute for readers’ visits to the original. The foundation acknowledges AI’s value in helping editors while urging respect for Wikipedia’s licensing conditions, including attribution and share-alike requirements. This is Wikimedia’s legal position, not a court ruling establishing the legality of AI training generally.
