Description

A technical benchmark that evaluates how 12+ frontier AI models handle a complex prompt to build a 3D Subway Surfers clone in a single shot. The analysis identifies Claude Opus 5 as a category-leading winner for implementing a true projected 3D engine, frame-rate independent physics, and advanced platformer affordances like coyote time and jump buffering from a single prompt.

Prompt

Create a fun endless runner game like Subway Surfers as a single HTML file using Canvas. Vertical canvas (400x700 or similar portrait mode), character runs automatically forward, swipe or space to jump, down arrow to slide. Collect coins, avoid obstacles like barriers and trains. Nice colorful city visuals with scrolling background, score based on distance, game over screen with restart. Keep it simple but visually appealing. Output only the full code.
