Cornell University researchers found that ChatGPT can memorize entire poems, raising ethical concerns about the training of AI models with potentially private data from the internet. The study, presented at the Computational Humanities Research Conference, focused on poems, which are short and present a copyright challenge. ChatGPT’s ability to recall poems evolved over time, sometimes refusing to provide copyrighted content. While the study concentrated on American poets, the next phase aims to explore how chatbots respond to requests in various languages and factors influencing memorization. Responsible and transparent use of powerful tools like ChatGPT is crucial, the researchers emphasized.
