Feed it a video with broken physics and Claude Opus 5.5 diagnoses exactly what's wrong, runs CFD and rod-mechanics simulations to compute the correct behavior, cross-checks the result with an independent finite-element solver, then re-renders the corrected motion back into the original scene. The side-by-side output is striking: a pendulum swinging with AI-invented motion on the left, replaced by a physically accurate one on the right. Built by @gokayfem, it's a full physics-correction pipeline driven entirely by the model.

Claude Opus 5.5 measures physics errors in video, then solves them with CFD and rod mechanics
An independent finite-element solver cross-validates the result before re-rendering
Output is a side-by-side video: broken AI physics vs. corrected real physics in the same scene
