Patronus AI on Wednesday released research showcasing how often leading AI models produce copyrighted content. “We pretty much found copyrighted content across the board, across all models that we evaluated, whether it’s open source or closed source,” Rebecca Qian, Patronus AI’s cofounder and CTO, said. “Perhaps what was surprising is that we found that OpenAI’s GPT-4 produced copyrighted content on 44% of prompts that we constructed.”
