A developer gave Opus 5.5 a minimal prompt — 'Build a fully procedural AAA quality kaiju simulation in three.js using pure TSL and modern techniques' — and the model autonomously worked for 3.5 hours, producing a kaiju simulation written entirely in pure three.js code. The prompt and interactive demo artifact are publicly available.
