Researchers have explored the relationship between internal denoising dynamics and external endpoint uncertainty in diffusion language models. By analyzing thousands of denoising trajectories across four models and four reasoning benchmarks, they found that stronger within-run concentration during denoising is associated with lower endpoint entropy, meaning more stable internal processes lead to more predictable outputs. This association is asymmetric, with high concentration almost always resulting in concentrated endpoints, while lower concentration can lead to varied outcomes. The study suggests that these within-trajectory dynamics can predict the variability of final outputs, potentially allowing for uncertainty estimation with fewer complete generations. AI
