AttuneBench evaluates emotional intelligence in language models using 200 multi-turn conversations between people and AI models. Participants annotated their own emotions, the model’s conversational behavior, and which responses they preferred. The benchmark measures several dimensions, including emotion tracking, response preferences, and conversation-wide understanding, rather than treating emotional intelligence as a single score. Its repository provides code to run and score evaluations, while the public site presents model results and analysis. The benchmark was developed through collaboration between Pareto AI and Thoughtful Lab.
