The report introduces three indices—the AI Frontier Index, the AI Infrastructure Index, and the AI Diffusion Index—to help policymakers, researchers, and industry leaders understand where breakthroughs are happening, where capacity exists to scale, and where AI is being used to improve lives.

Frontier builders — the inventors and pioneers who push the boundaries of what is possible. In AI, these are the researchers and model creators expanding the limits of intelligence. Infrastructure builders — the engineers, entrepreneurs, and institutions who scale breakthroughs through networks, tools, and skills. In AI, infrastructure builders provide the compute and connectivity that make large-scale intelligence possible. Users — the individuals, companies, and governments who use, adapt and apply new technologies to solve real-world problems.
