Researchers led by Lixing Tan introduced PhyEvolve, a three‑agent system that rewrites text‑to‑video prompts to include explicit physical state changes. The agents – Director, Physical Evolver, and Composer – plan causal transitions and feed them to existing video generators without retraining. Tests on four major benchmarks show an average 7.9‑point gain over the previous best agentic method.
Why it matters
Creators can get videos that follow realistic physics without needing new AI models.
