Introduction to theAI Index Report 2023Welcome to the sixth edition of the AI Index Report! This year, the report introduces more original data than anyprevious edition, including a new chapter on AI public opinion, a more thorough technical performance chapter,original analysis about large language and multimodal models, detailed trends in global AI legislation records,a study of the environmental impact of AI systems, and more.The AI Index Report tracks, collates, distills, and visualizes data related to artificial intelligence. Our mission isto provide unbiased, rigorously vetted, broadly sourced data in order for policymakers, researchers, executives,journalists, and the general public to develop a more thorough and nuanced understanding of the complex field ofAI. The report aims to be the world’s most credible and authoritative source for data and insights about AI.From the Co-DirectorsAI has moved into its era of deployment; throughout 2022 and the beginning of 2023, new large-scale AI modelshave been released every month. These models, such as ChatGPT, Stable Diffusion, Whisper, and DALL-E 2, arecapable of an increasingly broad range of tasks, from text manipulation and analysis, to image generation, tounprecedentedly good speech recognition. These systems demonstrate capabilities in question answering and thegeneration of text, image, and code unimagined a decade ago, and they outperform the state of the art on manybenchmarks, old and new. However, they are prone to hallucination, routinely biased, and can be tricked intoserving nefarious aims, highlighting the complicated ethical challenges associated with their deployment.Although 2022 was the first year in a decade where private AI investment decreased, AI is still a topic of greatinterest to policymakers, industry leaders, researchers, and the public. Policymakers are talking about AI morethan ever before. Industry leaders that have integrated AI into their businesses are seeing tangible cost andrevenue benefits. The number of AI publications and collaborations continues to increase. And the public isforming sharper opinions about AI and which elements they like or dislike.AI will continue to improve and, as such, become a greater part of all our lives. Given the increased presence ofthis technology and its potential for massive disruption, we should all begin thinking more critically about howexactly we want AI to be developed and deployed. We should also ask questions about who is deploying it—asour analysis shows, AI is increasingly defined by the actions of a small set of private sector actors, rather than abroader range of societal actors. This year’s AI Index paints a picture of where we are so far with AI, in order tohighlight what might await us in the future.Jack Clark and Ray Perrault
