NeurIPS 2025's top 50 paper contributors show China and the US neck-and-neck.

In the US, corporate labs—Google DeepMind, Meta, Microsoft—now rival top schools like Stanford, CMU, MIT, showing a major shift to industry-led AI research.

China’s leaders remain academic: Tsinghua, CAS, Peking, SJTU, HKUST. Singapore (NUS, NTU), Korea (KAIST), UAE (MBZUAI), and Canada (Mila) hold strong.

Europe trails, with only Oxford, EPFL, ETH Zurich, and TUM from the EU-27 making the list.
