Stanford University's AI Vibrancy Tool distills several metrics, from research output to talent attraction into a single view of how developed and competitive a country's AI ecosystem is. It's a snapshot of where innovation and talent is growing, and where governments are putting real weight behind AI.

High-income countries dominate the top ranks, reflecting deep investments in R&D, robust university systems and mature digital infrastructure. India is the only lower-middle-income country to break into the top 30, a sign of its expanding research base and large technical workforce. Brazil, China and Malaysia represent the upper-middle tier, each building out their Al capabilities with state-backed initiatives and growing private-sector activity.
