I gave Opus 5.5 one prompt: "Throw a haunted Halloween party: a mansion on a hill, a path of jack-o'-lanterns, ghosts in the sky, and guests in costume arriving." It built all of it in one HTML file. 26 jack-o'-lanterns, 9 ghosts, 28 bats, a graveyard, and a party already going inside. No 3D models, no engine. Happy Halloween.
