Opus 5.5 made tiny worlds. Sonnet 5.5 made a character. Same prompt: 20 frames of the Claude Code mascot, rebuild it in three.js. One try each, no fixes. Opus on top. → Opus, 27 min: every keycap holds a world with water, snow and lava → Sonnet, 15 min: the creature reads in every single shot → Opus built the giant out of 700 tiny creatures, watch 0:18 → then Opus lost its own mascot in the grass Fan-made recreation. Neither model saw its page run, I only rendered what they wrote. be honest, which one would you ship?
