banteg challenges AI models to beat his 3,819-step Sokoban solution — credit to the winner

banteg · x · 2026-11-11

Developer banteg is running a challenge for AI models: the full Heroes of Sokoban trilogy takes between 3,000 and 3,064 keys, and he can't close the last 64. Starting from 3,819 keys, he'll credit the best solutions models find in their realtime runs while holding out his own optimal solutions; beating a proven minimum would break his proof. Solutions are verified against the original game — a fun stress test of model planning and reasoning.
