New Test Shows How AI Videos Learn Real‑World Physics
Ever wondered if a computer can tell the difference between a ball that rolls naturally and one that flies off a table for no reason? Scientists introduced a clever, training‑free test called LikePhys that does exactly that. By feeding AI video generators pairs of short clips—one that follows the laws of physics and one that breaks them—the test measures which version the model thinks looks more plausible. Think of it like a “spot‑the‑fake” game for machines, similar to how we can instantly tell if a cup is about to tip over or not. The result, a score named Plausibility Preference Error, lines up closely with what people actually prefer, proving the AI’s “intuition” is improving. While today’s models still stumble on c…

Ever wondered if a computer can tell the difference between a ball that rolls naturally and one that flies off a table for no reason? Scientists introduced a clever, training‑free test called LikePhys that does exactly that. By feeding AI video generators pairs of short clips—one that follows the laws of physics and one that breaks them—the test measures which version the model thinks looks more plausible. Think of it like a “spot‑the‑fake” game for machines, similar to how we can instantly tell if a cup is about to tip over or not. The result, a score named Plausibility Preference Error, lines up closely with what people actually prefer, proving the AI’s “intuition” is improving. While today’s models still stumble on chaotic scenes like swirling water, they get better as they grow bigger and are given more time to think. This breakthrough brings us closer to AI that can safely simulate real‑world events, from virtual training to movie special effects. Imagine a future where every digital scene obeys the same physics we live by—because now, the machines are learning it too. Exciting, isn’t it?
