Ask ChatGPT to find a well-known poem and it will probably regurgitate the entire text verbatim – regardless of copyright law – according to a new study by Cornell researchers.

The study showed that ChatGPT, a large language model that generates text on demand, was capable of “memorizing” poems, especially famous ones commonly found online. The findings pose ethical questions about how ChatGPT and other proprietary artificial intelligence models are trained – likely using data scraped from the internet, researchers said.
