AI Diffusion Models Rearrange, Not Reinvent
Diffusion models power image generators like DALL·E and Stable Diffusion, producing stunning, lifelike pictures from simple text prompts. But a recent study led by researchers at the Katz School of Science and Health asks a fundamental question: Are these models really creating something new or just rearranging what they’ve already seen?
