View on XOPUS AND ASTRA BUILT THEIR OWN CASTLES. WHO DID IT BETTER? I asked Claude Opus 5.5 and ChatGPT-6 Astra to create their own medieval castles: choose the architecture, design a coat of arms, and fly their own banners Opus built an entire kingdom: red rooftops, a moat, a village, and surrounding mountains. Astra went with a pale stone island citadel, emerald banners, and an eight-pointed star Both castles are built with code using Three.js + WebGL: procedural geometry, waving banners, patrolling guards, working drawbridges, and changing lighting. Everything is interactive and runs right in your browser Opus on the left - $11.15. Astra on the right - an estimated $7.07 at API rates, including revisions Which kingdom would you live in? 👇
