OPUS 5.5 VS SONNET 5.5: WHO BUILDS BETTER AI SIMULATIONS?

OPUS 5.5 VS SONNET 5.5: WHO BUILDS BETTER AI SIMULATIONS? We benchmarked Claude Opus 5.5 and Sonnet 5.5 on a complex biomorphic coding task: building a full X-Ray fly simulation (Musca Domestica) from scratch. Both models ran with zero console errors, but their architecture choices revealed two completely different paradigms. 1. Claude Opus 5.5 - The 3D & UX Powerhouse: • Spatial 3D Scene: Built a true Three.js 3D model with glowing X-ray contours, free orbital camera controls, and automatic object tracking. • Complete Interactive UI: Includes pause, speed adjustment (0.5× / 1× / 2×), direct stage scrubbing, and an 11-stage 70s cycle. • Frame-Driven Sync: Time tracks rendered frames-smoothly pausing when the browser tab is unfocused. 2. Claude Sonnet 5.5 - The Deep Telemetry Instrument: • Granular 2D Schematics: Traded 3D space for dense analytical UI-featuring neural impulse graphs, target crosshairs, and live organ metrics. • Advanced Neuro-Logic: 14 distinct stages covering…
