About

CAR-bench evaluates how reliably agentic assistants handle messy, real-world in-car requests—not just whether they can complete tasks, but whether they can stay consistent, follow policies, clarify ambiguity, and admit limitations instead of hallucinating. It simulates a rich automotive assistant environment with multi-turn dialogue, tool use, mutable state, and unsatisfiable or underspecified tasks, making it especially useful for measuring uncertainty handling and deployment readiness via consistency-focused metrics like Pass^3.
