A Munich court has ruled that OpenAI infringed German copyright law by using song lyrics to train its artificial intelligence models and reproduce them in chatbot outputs. This marks the first major case of its kind in Europe.

• The court found that both the memorization in language models and reproduction in chatbot outputs constituted copyright infringement.
• The lawsuit was filed by the German music body GEMA, representing artists behind nine German songs.
• GEMA has over 100,000 composers, songwriters, and publishers as members.
