Sourced Reporting & Contextual Benchmarks
• ABC News Report: "As the world debates the risks of AI, China closes the technology gap with the US" (ABC News Tech Desk). The US has historically outpaced all competitors in compute scale and model performance, but citation volume and high-velocity patenting have sharply narrowed the gap.
• Stanford AI Index Data: China accounted for 20.6% of global AI research citations (vs US 12.6%) and 74.2% of patent grants. However, US models retain leading performance margins (~2.7% margin in flagship frontier benchmarks) supported by private compute and investment advantage ($109B+ private AI investment).
• Methodology Note: Capability indices model baseline starting scores (US: 92.5, China: 78.0) scaled across compute availability, citation velocity, and model capabilities. Crossover year calculates the first trajectory intersection.
