Stanford 2026 AI Index Report: US-China AI Gap Narrows to 2.7%, Chinese Models Enter Global Top 10

Stanford released the 2026 AI Index Report, a 423-page document revealing new changes in the global AI landscape. The performance gap between US and Chinese AI models has shrunk to 2.7%—China's Dola Seed 2.0 is close to US Claude Opus 4.6, and four Chinese entities including DeepSeek and Tsinghua enter the global top 10. The report also notes 90% of top models come from industry, AI has a 'jagged frontier' (winning math Olympiad but only 50% accuracy in reading analog clocks), 20% fewer software developer jobs for 22-25 year olds, and global AI investment reaches $581.7 billion.
