Anthropic says its new Fable 5.2 model has much better robot control skills

Anthropic's official Claude account on X posted on 10 November that its new AI model, Fable 5.2, has greatly improved skills for controlling physical robots, as part of a performance introduction for the model.

The improvement shows even on tasks the model was not explicitly trained for, the company said. On RoboDojo, a benchmark that evaluates dual-arm robots in simulation, Fable 5.2 beat other models and most AI systems built specifically for robot control, according to the post.

The robot news site Robotstart, which reported the post, noted the gap between simulation results and stable operation on real machines, and said independent user experience will be one to watch.
