Sonnet 5 vs Fable 5 vs GPT-5.5 vs Gemini - write a cyberpunk alley in Three.js from scratch, one shot

Claude Sonnet 5 shipped yesterday, so I've re-run this threejs benchmark - a neon cyberpunk alley in the rain. It's one shot, so no edits, and exactly the same prompt for each model. Same locked 10-second camera dolly for all of them, so the only variable is the code each model wrote.
