Code-as-World VL Demo

Code as Worlds introduces executable world representations for physical reasoning. This demo showcases the Code-as-World-VL vision-language model, which performs quantitative physical reasoning from videos — estimating object sizes, velocities, and distances from visual evidence.

Usage

1. Upload a short video clip.
2. Enter a physics measurement question (e.g. "What is the length of the object in cm?").
3. Optionally provide prior information (e.g. "ruler calibre = 1 cm") that helps ground the measurement.
4. Click Analyze and the model streams its numerical answer.

Example assets

Example videos are from the QuantiPhy validation set (CC-BY-4.0). Questions and priors are drawn from the same dataset.
