Researchers from NVIDIA, MIT and the University of Oxford released Physis‑Lang, a self‑evolving physical language for AI. The system lets a video‑world model reason about physics by using language instead of extra visual or numeric cues. In tests, Physis‑Lang lifted the Cosmos‑3 model’s score above the previous best Veo‑3.1 on standard physics benchmarks. The work was posted on Sep 30, 2026.

## The facts

- Cosmos‑3 outperformed Veo‑3.1 on physics benchmarks after adding Physis‑Lang
- Research team includes NVIDIA, MIT and Oxford

## Why it matters

Better physical reasoning can make AI‑generated videos look more realistic and reliable.
