Diffusion models' image generation: copying vs. originality explored in NeurIPS paper

By PulseAugur Editorial · [1 sources] ·

A recent NeurIPS 2025 best paper investigated whether diffusion models simply copy their training data. Researchers trained small diffusion models on 1,024 face photos and observed their outputs. At 100,000 training steps, the models generated novel faces without replicating any training images. However, when training extended to 1.62 million steps, approximately 34% of generated samples were found to be copies of training data. AI

IMPACT Investigates the memorization capabilities of diffusion models, relevant for understanding AI-generated content originality.
