BudgetPix: Compute-Adaptive Tokenization for Pixel-Space Image Diffusion

Most image generation models rely on uniform tokenization, allocating the exact same computational budget to equally-sized image patches. This static paradigm cannot adapt to different resource constraints at inference time, and yields suboptimal quality-cost tradeoff by devoting the same effort to both plain backgroun...

Predictive Structure Improves Video Diffusion Dynamics

Experiments show that LDO substantially improves physical commonsense, object permanence, and trajectory fidelity while preserving visual quality, suggesting that predictive latent supervision offers a practical route to make video generators not only photorealistic but also physically legible.
