LATTE uses selected latent states from diffusion denoising, fusing each with image features for classification. Unlike LaRE’s single-step reconstruction-error feature, it combines a sequence of model responses. On GenImage, trained on SDv1.4 images, it reaches 91.0% average accuracy across eight generator subsets, versus 86.9% for AIDE; this benchmark does not establish performance on arbitrary future generators.
