As AI systems play an increasing role in individual and collective decision-making, understanding how they can respond effectively and safely to societal needs – and contribute to greater human well-being – has become a key policy concern. This raises fundamental questions: What defines AI capabilities, and how can these capabilities be aligned with individual and collective well-being? How can such capabilities and their impacts be measured and benchmarked using evidence-based approaches? Watch this webinar organised by the OECD Centre for Well-being, Inclusion, Sustainability and Equal Opportunity (WISE), in collaboration with the OECD Education Directorate and the OECD Science, Technology and Innovation Directorate that gathered experts from international organisations, academia and industry to discuss the definition and measurement of AI capabilities and well-being.
