backStanford University’s AI Index 2025 confirms the United States’ leadership in artificial intelligence, with 40 top-tier models released in 2024—well ahead of China’s 15 and Europe’s 3. Still, China leads in scientific publications and patent filings, signaling its growing influence in the field. Notably, China’s DeepSeek-R1 model is already competing with American frontrunners despite operating with significantly fewer computational resources.
A striking finding in the report is the dramatic drop in the cost of running AI models with GPT-3.5-level performance: from 2022 to 2024, costs fell by a factor of 280. This cost reduction is democratizing access to advanced AI technologies and enabling broader global participation. While the race for dominance continues, the report signals a shift toward a more distributed AI ecosystem—provided that emerging players can align technological ambition with strong public policy and local technical capacity.
