APEX adapts condition shifting to streaming video generation, using the same model for generation and fake-distribution estimation by negating the projected text condition. It retains the frozen teacher and S2-Avatar’s replay training. In matched training settings, iteration time fell 9.2% and peak memory 4.4%; instruction-following preference improved, but motion preference favored S2-Avatar and benchmark quality was mixed.
