Synthetic User Simulation(SIM)
An LLM-driven user simulator, parameterized by diverse personas such as confused, adversarial, impatient, or goal-shifting users, is used as a test harness that autonomously drives a conversational agent through many multi-turn dialogues. Running these simulated conversations at scale surfaces dropped context, policy violations, and hallucinations before real users encounter them, exploring branches of the dialogue tree that static single-turn golden cases cannot reach. It requires deliberate persona diversity and goal alignment to avoid the blind spot of a single cooperative simulator that behaves more agreeably than real users. Distinct from tau-bench, a fixed benchmark that embeds one user simulator, and from eval-driven-agent-development, whose goldens are static single-turn cases while this generates dynamic multi-turn traffic.
