The first open benchmark measuring AI's impact on human well-being across physical, psychological, and societal dimensions.
Measuring AI's impact on people
Today's AI benchmarks measure what models can do: accuracy, reasoning, task completion. They say almost nothing about what AI does to the people who rely on it. Two models with identical capability scores can shape a user's autonomy, mental health, and relationships in completely different ways, and the field has had no shared way to tell them apart. ImpactBench is built to answer a different question: across realistic, multi-turn conversations, does an AI system support or undermine human flourishing?
