A small design test between two Claude models. The brief, identical for both: animate a contemporary house being built from an empty site, through the foundation, structural frame, glazing and roof, to warm interior lights coming on at dusk. It should read like an architectural studio's design reel. The constraints: one HTML file with three.js as the only library, 1080×1080, and a 10-second seamless loop. Each model got one attempt, the code was not edited, and both were rendered through the same pipeline. Which one would you ship, A or B? I'll reveal the models in the replies once the poll closes.
