Is it legal to train AI models on copyrighted books? It’s complicated

AI models like ChatGPT, Gemini, and Claude are trained on vast databases of published works, including copyrighted books and online articles, often without authors' knowledge or consent. This practice raises questions about its legality and potential impact on authors' livelihoods. While some legal rulings might favor AI companies, the ethical implications and the scale of potential revenue for these companies, such as an estimated $200 billion by 2028, highlight the complexity of the issue.
