About
π-bench is a deterministic, multi-turn benchmark that evaluates AI agents’ policy compliance across nine diagnostic dimensions (e.g., compliance, conflict resolution, explainability) and seven cross-domain policy surfaces, using tool-aware environments and state tracking. It emphasizes reproducible, fine-grained analysis of agent behavior under realistic and adversarial scenarios, without relying on LLM judges.
