PHYSIX OBSERVATION

Behind the price war is a key inflection point as AI video shifts from a novelty tool to a productivity tool. When the generation success rate rises from 20% to 90%, cost reductions only truly matter then. Vendors are seeking a balance between cost-effectiveness and performance, but industries like short dramas need more affordable, standardized production solutions.
