A maze benchmark tests models’ spatial memory and tool use with 45° moves

The author built a maze benchmark to test models’ spatial awareness, memory, and tool use. The environment requires finding a key, opening a door, and then escaping, with observations generated after each action.

To make the task tractable, the benchmark provides tools such as moving forward/backward, turning in 45° increments, opening doors, and picking up items. The author also adds extra clarity about crossable tiles after models got lost. Early runs show GPT-5.4 mini and GLM-5.2 looping, while K2.6 completed it more efficiently. GLM-5.2 consumed about 62 million tokens, versus 9 million for K2.6, though the author notes this is not a fair direct comparison because thinking preservation settings differed.
