3D Flappy Bird · AI Comparison

One brief.
Three models.

Each AI model was given the same task — build a 3D Flappy Bird in the browser — and full creative freedom over art direction, physics, and sound. These are their answers, untouched. Pick one and fly.

Claude Fable 5 Paperwing An origami bird gliding through a hand-folded paper world — washi textures, soft daylight, and a koto-tinged soundscape.
Gemini 3.5 Flash · high Cyber Flight A neon quantum grid at full speed — synthwave skyline, glowing gates, and procedurally synthesized audio.
GPT-5.5 · xhigh Flappy Bird 3D A clean, pastel-sky take built with TypeScript and Vite — calm daylight palette, crisp HUD, and tight one-button physics.
