GPT-6 Astra Broke a Robot Gripper in a Real-World LEGO Grasping Test

A team ran OpenAI's GPT-6 Astra through a custom agent-control harness on physical robot arms and snapped a gripper — a reminder that frontier reasoning doesn't transfer cleanly to atoms.

A team ran GPT-6 Astra through a custom agent-control harness on YAM robot arms for a LEGO grasping task — and broke a gripper, according to @paigeinsf. The failure is more instructive than a success would have been. It illustrates the persistent gap between a model's linguistic and reasoning competence and its ability to control physical hardware where force, timing, and feedback matter.
