REUTERS — The University of California, Berkeley School of Law is among the first law schools to adopt a formal policy on student use of generative artificial intelligence such as ChatGPT. The policy, rolled out April 14, allows students to use AI technology to conduct research or correct grammar. But it may not be used on exams or to compose any submitted assignments. And it can’t be employed in any way that constitutes plagiarism, which Berkeley defines as repackaging the ideas of others.
