According to the 2025 Artificial Intelligence Index Report by Stanford University, the United States led in producing notable AI models in 2024, releasing 40 models.
China followed with 15, and Europe contributed 3. Industry dominance was evident, with nearly 90% of these models originating from corporate entities, up from 60% in 2023.
Academia's contribution declined, producing no notable models in 2024. Despite the U.S.'s lead in quantity, China's models have closed the performance gap, achieving near parity on benchmarks like MMLU and HumanEval.
This shift underscores the intensifying global competition in AI development.
