A simple way to measure bias in video models uses one prefix and many continuations
Kangwook_Lee · x · 2026-08-04
A simple method for studying bias in video models is to give a model a prefix video with several plausible next scenes, then sample many continuations.
The author argues this matters even more as video models evolve into foundation models for action, or “World Action Models,” because their default continuations can reveal systematic behavioral bias.
