ChatGPT Reportedly Found to Reproduce Protected German Lyrics in Copyright Case

AI Incident Database · article · Nov 11, 2025 · UTC

The court reportedly found both memorization of nine songs and lyric output to infringe exploitation rights. OpenAI disputes the ruling and may appeal. Damages were ordered, with implications for AI training on copyrighted works.
