Simulated Users and Self-Play for Interactive Evaluation
Simulated Users and Self-Play for Interactive Evaluation refer to techniques where AI models, such as large language models (LLMs), act as both users and agents in interactive scenarios. This allows for automated, scalable testing of conversational abilities, task completion, and decision-making. By simulating user interactions and self-play, developers can systematically evaluate and improve LLM performance, identifying weaknesses and optimizing responses without relying solely on human evaluators.

❓ Frequently Asked Questions
What are simulated users in interactive evaluation?
Simulated users are artificial agents that imitate human interactions with a system, allowing automated testing of interfaces, dialogs, or workflows without real participants.
What is self-play and why is it useful here?
Self-play lets an agent interact with copies of itself to generate diverse strategies and scenarios, helping evaluate robustness and reveal edge cases.
How do simulated users and self-play complement real-user testing?
They scale testing, provide repeatable baselines, and explore rare interactions, while real users validate realism and satisfaction.
What should you watch out for when using simulated users?
Be aware of mismatches with real users, potential bias or determinism, and overfitting to the simulator; mitigate with realism checks, stochastic behavior, and occasional human validation.
