Crossy Road AI Clone Comparison

A side-by-side coding benchmark of Haiku 5.5, Gemini 3.8 Flash, and Luna 6

Crossy Road clone

Description

A comparative test where three frontier AI models were tasked with building a playable Crossy Road clone from scratch using vanilla JavaScript. The experiment tracks development time and output quality, noting that Haiku 5.5 delivered a smooth game in 35 minutes while Luna 6 failed to produce usable code.
