APEX Method Reduces Streaming Video Generation Costs via Condition Shifting
November 9, 2026
APEX enables few-step streaming video generation by using condition shifting to estimate the velocity field within the generator. This method removes the need for an independent fake-score network, reducing training memory and computation while maintaining performance on 180-second videos.
HOW THIS AFFECTS YOU
●
builderYou can generate longer video streams with less memory and compute requirements.
●
researcherYou can avoid the extra overhead of tracking evolving generators in DMD-style training.
