## Summary

A survey examines video foundation models and video world models through the unifying lens of world modeling, organizing the literature into four complementary operations: reading, which infers world properties from observed video; writing, which synthesizes video from specified or learned conditions; sharing, which integrates understanding and generation through common modeling mechanisms; and interacting, which predicts and updates world states under actions and observations.
