Explorable voxel world (Fable 5.1 vs Fable 5)
Claude Fable 5.1 and Fable 5 each got one attempt at an open voxel-world prompt. Fable 5.1 built a floating island called Aerie with a windmill, a lighthouse, a red-roofed village, a waterfall, birds and a day-night cycle; Fable 5 built a pastel island with sheep, a pond and blossom trees.
Prompt
Quoted verbatimSelf-contained
Build an explorable 3D voxel world. It must be viewable from the outside, with the ability to rotate around it and zoom, and it must contain things that move on their own so it feels alive rather than static. What the world is, what lives in it, and how it looks is entirely up to you. Everything about the design is your decision: style, colors, mood, environment, camera, level of detail, and any extra touches. Do not ask me any questions, make every choice yourself and build the most impressive version you can in a single attempt. Technical requirements: one single self-contained HTML file, no external models, images, sounds, or asset URLs of any kind (a JavaScript library from a CDN is fine). It must start running on its own the moment it loads, with no clicks needed, and run smoothly with no console errors.
