OpenAI's Sora 2: a "World Simulator" that creates videos respecting the laws of physics.
What it is
AI video generation from text.
Sora 2 is designed as a "World Simulator" that can model complex physical interactions and object permanence. The model creates realistic videos that respect the laws of physics. For example, a video of a backflip on a paddleboard with a correctly calculated buoyancy force, or a basketball that bounces realistically off the rim after a missed shot. This suggests that the model contains an internal physics model rather than mere pixel morphing.
What it does
What it does
- World Simulator: an internal physics model simulates gravity, buoyancy and collisions
- Complex physical interactions with the correct forces
- Object permanence: objects stay the same over time
- Mandatory hidden origin marking (C2PA) and visible watermarks
- Strict testing against deepfakes, invite-only rollout
Good for
- Physically realistic videos (sport, action scenes)
- Creative and artistic projects with visual effects (VFX)
- Simulating and visualising complex scenarios
Not for
- Immediate production rollout: access is invite-only and limited
Our verdict
The top in physical realism thanks to the "world simulator" approach. Cautious rollout and watermarks limit availability, though.
Why we use it
We use Sora 2 Video for creating realistic videos with physical accuracy. The model excels at simulating the laws of physics and object permanence. It suits creative video where we need realistic physical interactions and a stable world. OpenAI is rolling the model out cautiously, invite-only and with strict testing for misuse (red-teaming).
Use cases
