Opus 5 burns 690M tokens to make a game; GPT-5.6 replicates it for $5

A user named Vyom used Anthropic's Opus 5 model with a 2,000-character prompt and 690 million tokens to generate an American-style water racing game called INK TIDE, costing about $423. Shortly after, another user, Anul Agarwal, replicated a similar game using GPT-5.6 Sol and Luna Max in Codex for only $5, though with lower fidelity. The article compares the two AI-generated games, highlighting the potential and differences in AI-driven game development.
