We identify and track contemporary and historic advances in AI, collating key details across several areas. This research includes who developed models, when, and for what tasks, how much compute was used for training, how many parameters models have, how much data was used for training, what hardware was used for training, and more.
Epoch AI is a multidisciplinary research institute investigating the trajectory and impact of artificial intelligence.
We publish datasets, data visualizations, research reports, and predictive models to analyze the forces shaping AI development. Our goal is to foster scientific dialogue and bring empirical rigor to predictions about the future of AI.
We’re proud to partner with select stakeholders on projects aligned with our mission.
