We put frontier reasoning models in simple 2D mazes. They solved 6/150.

Discussion

We built MultiNet 2.0 to study how frontier models behave over long-horizon interactive tasks.

The environments are deliberately simple: 2D mazes that are trivial for humans, but require models to repeatedly perceive, reason, act, and keep track of progress.

Across 150 evaluation runs, the models solved just 6!

Before looking at the results, try one yourself:

Test your might against the machine!
