A chatbot model learned to measure a box with a tape measure: Claude Fable 5.2 tops a real robot-arm test, while Gemini breaks a gripper ↗
Independent benchmarker Artificial Analysis says Anthropic's Claude Fable 5.2 now leads its real-world robot-arm benchmark, AA-Robotics v0.1, with a score of 75, ahead of GPT-6 Astra at 69, and is the first model to score on the 'measure the box' task by using a tape measure's markings in video as a scale. The firm also said Google's Gemini 4 Carbon broke one of its grippers.
