Frequently Asked Questions

Is Sora a World Model?
Partially. Sora understands basic physics (gravity, reflections, fluids) but doesn't have complete world understanding. OpenAI describes it as a 'world simulator'.
What are World Models used for?
Robotics (understanding physical environment), autonomous driving (predicting other vehicles), and video generation (realistic physics).
