Prompt Tested
The man opens the book, flicks through the pages, stops, and lays it flat to read.
What Are We Looking For?
What sounds simple quickly exposes how well these models understand hands, motion, and physical reality. Assuming you are human, you have seen this through your own eyes and know how it should look. Good news is none returned a hand with extra fingers!
Kling3.0
Hands interact correctly
Pages flick (slightly clumsy, but believable)
Rated Green as compared to other model results
LTX2.3
Pages move unnaturally
Cover opens "magically"
Focus shifts
Wan2.2
Natural opening
Only turns one page (fails task)
Seedance2.0
Motion feels real
Hallucinates an extra hardback cover — could be cleaned up by a compositing artist
The Verdict
Most models are still struggling with:
- Physical consistency
- Following sequential actions
- Maintaining believable object behavior
Kling and Seedance came close on this go-around, but still imperfect.
