2025年AI指数报告2025

Introduction to theAI Index Report 2025 Welcome to the eighth edition of the AI Index report. The 2025 Index is our most comprehensive to date and arrives at animportant moment, as AI’s influence across society, the economy, and global governance continues to intensify. New inthis year’s report are in-depth analyses of the evolving landscape of AI hardware, novel estimates of inference costs, andnew analyses of AI publication and patenting trends. We also introduce fresh data on corporate adoption of responsible AIpractices, along with expanded coverage of AI’s growing role in science and medicine. Since its founding in 2017 as an offshoot of the One Hundred Year Study of Artificial Intelligence, the AI Index has beencommitted to equipping policymakers, journalists, executives, researchers, and the public with accurate, rigorously validated,and globally sourced data. Our mission has always been to help these stakeholders make better-informed decisions about thedevelopment and deployment of AI. In a world where AI is discussed everywhere—from boardrooms to kitchen tables—thismission has never been more essential. The AI Index continues to lead in tracking and interpreting the most critical trends shaping the field—from the shiftinggeopolitical landscape and the rapid evolution of underlying technologies, to AI’s expanding role in business, policymaking,and public life. Longitudinal tracking remains at the heart of our mission. In a domain advancing at breakneck speed, the Indexprovides essential context—helping us understand where AI stands today, how it got here, and where it may be headed next. Recognized globally as one of the most authoritative resources on artificial intelligence, the AI Index has been cited in majormedia outlets such as The New York Times, Bloomberg, and The Guardian; referenced in hundreds of academic papers;and used by policymakers and government agencies around the world. We have briefed companies like Accenture, IBM,Wells Fargo, and Fidelity on the state of AI, and we continue to serve as an independent source of insights for the global AIecosystem. Message From the Co-directors As AI continues to reshape our lives, the corporate world, and public discourse, the AI Index continues to track its progress—offering an independent, data-driven perspective on AI’s development, adoption, and impact, across time and geography. What a year 2024 has been for AI. The recognition of AI’s role in advancing humanity’s knowledge is reflected in Nobel prizes inphysics and chemistry, and the Turing award for foundational work in reinforcement learning. The once-formidable Turing Testis no longer considered an ambitious goal, having been surpassed by today’s sophisticated systems. Meanwhile, AI adoption hasaccelerated at an unprecedented rate, as millions of people are now using AI on a regular basis both for their professional workand leisure activities. As high-performing, low-cost, and openly available models proliferate, AI’s accessibility and impact are setto expand even further. After a brief slowdown, corporate investment in AI rebounded. The number of newly funded generative AI startups nearlytripled, and after years of sluggish uptake, business adoption accelerated significantly in 2024. AI has moved from the marginsto become a central driver of business value. Governments, too, are ramping up their involvement. Policymakers are no longer just debating AI—they’re investing in it. Severalcountries launched billion-dollar national AI infrastructure initiatives, including major efforts to expand energy capacity tosupport AI development. Global coordination is increasing, even as local initiatives take shape. Yet trust remains a major challenge. Fewer people believe AI companies will safeguard their data, and concerns about fairnessand bias persist. Misinformation continues to pose risks, particularly in elections and the proliferation of deepfakes. In response,governments are advancing new regulatory frameworks aimed at promoting transparency, accountability, and fairness. Publicattitudes are also shifting. While skepticism remains, a global survey in 2024 showed a notable rise in optimism about AI’spotential to deliver broad societal benefits. AI is no longer just a story of what’s possible—it’s a story of what’s happening now and how we are collectively shaping thefuture of humanity.

AI performance on demanding benchmarks continues to improve.In 2023, researchers introduced newbenchmarks—MMMU, GPQA, and SWE-bench—to test the limits of advanced AI systems. Just a year later, performance sharplyincreased: scores rose by 18.8, 48.9, and 67.3 percentage points on MMMU, GPQA, and SWE-bench, respectively. Beyondbenchmarks, AI systems made major strides in generating high-quality video, and in some settings, language model agents evenoutperformed hum
