3D Solar System Head-to-Head

The same Three.js prompt given to Opus 5.5 and MiniMax M3.1 Flash, each producing a draggable, rotatable 3D solar system with particle nebulae and planetary halos, where clicking a planet flies the camera to it. A screen recording comparing the two results; the author notes the latter also fixes its own rendering issues and adds a control panel. About 60 seconds, good for model benchmarking or an interactive astronomy explainer.
