    Summary

    Generative video models burn compute predicting every pixel of the future, including details nobody needs. JEPA (Joint-Embedding Predictive Architecture) predicts in representation space instead: mask part of the input, predict the embedding of the missing part, and skip pixel reconstruction entirely. That is also why meaning-space search works: retrieval compares embeddings of scenes, not raw frames.
