CausaLab: A Scalable Environment for Interactive Causal Discovery Toward AI Scientists

Junlin Yang, Dylan Zhang, Xiangchen Song et al.

What this work does

Samples hidden SCMs, permits bounded interventions and asks agents for both held-out predictions and an explicit graph/mechanism description.

Connection to discovery

A close benchmark for measuring whether successful answers are backed by recovered mechanisms and appropriate experiments.

Evidence

Comparisons distinguish task accuracy from edge and mechanism fidelity, including cases where topology is preserved but changed functional forms break prediction.

Scope and limitations

The variables, mechanisms and intervention interface are generated within a known family. High prediction accuracy is insufficient evidence of mechanism recovery; real-world causal sufficiency remains outside the simulator.
