Sailing Simulation Challenges AI Models

⊲ XDA Developers ⊳ A Reddit user, abhi3188, has used Claude Code to build a sailing simulator in which large language models race a virtual yacht. Every five seconds each model receives 23 raw numbers describing heading, speed, wind and the next mark, then sets its helm and sails, with no sailing advice and the clock paused while it reasons. Gemini 4 Argon won easily at roughly a fifth of GPT-6 Astra’s token cost, GPT-6 Astra placed second, Claude Opus 5.5 stalled and timed out, and Qwen 3.5-9B headed for a beach.
◂ Gemini 4 Argon’s win at a fifth of GPT-6 Astra’s token cost suggests simulation could become a practical yardstick for choosing models for spatial tasks. ▸
