Following the Fable 5.1 release, developers have launched Mazebench, the world's toughest 3D spatial reasoning evaluation.
- Scale: A single run could take weeks and consume billions of tokens.
- Context: Fable 5 scored only 1% on this benchmark without Python.
The test aims to challenge the model's limits in high-dimensional spatial reasoning and long-horizon task handling.
