Hidden trade-off in video world models: geometry vs scale
keenanisalive · x · 2026-09-02
The author compares Atlas and Meshy 7, highlighting a hidden trade-off in video-based world models.
- Meshy 7: Has much more fine-grained shape understanding at the object scale.
- World Models: Stronger in time and larger spatial scales but lack fine geometry.
- Analysis: It's not a total victory but a different allocation of network capacity, which is hard to catch with human vision alone.
