NVIDIA Researchers Introduce Physis-Lang: Self-Evolving Physical Language That Lifts Cosmos 3 Past Veo 3.1 on Physics Benchmarks
NVIDIA's Physis-Lang physics captions lift Cosmos 3 past Veo 3.1 on several physics video benchmarks.
NVIDIA, MIT, and University of Oxford researchers introduce Physis-Lang, a self-evolving natural-language representation of physics used for video-data curation, training captions, and inference prompts. On the September 29, 2026 Physics-IQ Verified snapshot, Cosmos3-Super with Physis-Lang scored 48.2 and Cosmos3-Nano scored 43.3; Cosmos3-Nano also beat Veo 3.1 on PhyGenBench (71.04 vs 65.63) and Physics-IQ Verified (43.41 vs 34.99) after LoRA fine-tuning. Distilling the captioning pipeline into Qwen3-VL-4B-Instruct models preserved most of a 7.05-point Wan2.1-14B gain at roughly $120 instead of about $24,120 in API cost. The comparison lists the work as paper-only as of September 30, 2026.
