Scaling Video Generation for Reasoning: At What Cost?

Weihang Guo, Xiaoyu Wu, Yifei Wang et al. · 2026

We study whether scaling video generation enables models to reason about hidden information from the past frames, and at what computational cost. Our controlled benchmark requires predicting nine prescribed moves of an initially solved 2x2x2 Rubik's Cube from a fixed view of three faces. Correct predictions require inf …

What Paired Evaluations Reveal under Visual Perturbations

Yongda Wei, Chen Zhang, Yifei Wang et al. · 2026

Robustness evaluation must examine diverse visual perturbations, while benchmarks cover only some real-world conditions and physical testing is costly. Paired evaluations link clean and perturbed predictions for the same image, capturing changes in correctness, confidence, and acceptance beyond aggregate accuracy. We i …
