  Welcome to the fifth edition of the AI Index Report! The latest edition
includes data from a broad set of academic, private, and nonprofit
organizations as well as more self-collected data and original analysis than
any previous editions, including an expanded technical performance chapter, a
new survey of robotics researchers around the world, data on global AI
legislation records in 25 countries, and a new chapter with an in-depth
analysis of technical AI ethics metrics.
  The AI Index Report tracks, collates, distills, and visualizes data related
to artificial intelligence. Its mission is to provide unbiased, rigorously
vetted, and globally sourced data for policymakers, researchers, executives,
journalists, and the general public to develop a more thorough and nuanced
understanding of the complex field of AI. The report aims to be the world's
most credible and authoritative source for data and insights about AI.
