On the MazeBench 3D spatial reasoning benchmark, GPT-6 "Astra" with code execution nearly doubled the score of GPT-5.6 "Sol" with code execution. Surprisingly, Astra without any tools still beat GPT-5.6 Sol with code execution.
The author calls Astra a powerful agent, though earlier runs show it still struggles with longer tunnels in 3D environments.
