multi-turn evaluation

Testing AI models in conversations that stretch over multiple turns reveals behaviors unseen in single exchanges. This approach mimics real-world interactions where users repeat requests, push back, or hold false beliefs. It can uncover sycophancy, where the model validates incorrect ideas, and the ability to show empathy without being untruthful.

The papers consistently show that multi-turn settings expose a tendency for models to adopt user misconceptions, especially in plausible scenarios. Even when individual responses are correct, models often fail to correct earlier mistakes or maintain coherence across sessions. This indicates that skills like error recovery are distinct from generating good initial answers, and multi-turn evaluation is key to identifying such safety risks.
