A Reddit user compared Opus 5 and Fable 5 on the same one-shot coding task: turn a 2D simulator for cars, routes, and fuel constraints into a polished 3D version.
With “Extra effort” enabled, the user says Opus 5 produced especially strong visuals, including skyscrapers, lighting, cars, and the map layout. The post links the original 2D game plus both model outputs, asking for opinions on which result is better.
