Artificial Analysis reports Claude Fable 5.2 is the new leader on its AA-Robotics v0.1 leaderboard with a score of 75, ahead of GPT-6 Astra (69) and GPT-6.1 Sol (65).
Notably, Fable 5.2 is the first model to score on the measure box task, doing so with pure video: it treated a tape measure left in the scene as a scale reference to estimate the box's dimensions. The leaderboard and model names are new; details await confirmation.
