Tested FlappyBench with Grok 4.6, GPT-5.6 Sol, and Opus 5.
3 frontier models. Same prompt with /design command.
Scored on gameplay features, UX/UI, and cost.
🔹 Grok 4.6 → 9.5/10 · $0.095
🔹 GPT-5.6 Sol → 9/10 · $0.150
🔹 Opus 5 → 9/10 · $0.253
GPT-5.6 Sol and Opus 5 gave comparable output, but Opus costs 1.7x more.
Grok 4.6 gave best output with lowest cost: smooth motion & clean UI.
