Overview
- IPV-Bench is a new benchmark for evaluating video understanding and generation models
- Tests models on "impossible videos" that violate physical laws or contain logical contradictions
- Includes 1,000 carefully crafted test prompts across 9 impossibility categories
- Reveals current state-of-the-art models struggle with physical reasoning and consistency
- Shows models often hallucinate impossibilities even when not prompted for them
- Provides a framework for making video generation models more reliable and trustworthy
Plain English Explanation
Imagine watching a video where water flows uphill, a ball bounces higher each time it hits the ground, or a car drives through a solid wall. These are "impossible videos" - they show events that can't happen in our real world because they break the laws of physics or contain lo...
