## ⚡ Quick Summary

Published by Stanford University, this report is the ninth edition of the AI Index, an independent initiative at the Stanford Institute for Human-Centered Artificial Intelligence (HAI). It compiles global data on AI’s development, performance, adoption, impacts, and governance across nine substantive chapters: research and development, technical performance, responsible AI, economy, science, medicine, education, policy and governance, and public opinion. Its stated purpose is to equip policymakers, researchers, executives, journalists, and the public with evidence for decisions about AI.

The report’s central finding is a widening gap between rapidly advancing AI capabilities and the readiness of governance frameworks, evaluation methods, education systems, and data infrastructure. It tracks more demanding tests of reasoning, safety, and real-world task execution, while warning that benchmarks are saturating and may be unreliable. Among its reported indicators, organizational AI adoption reached 88%; industry produced more than 90% of notable frontier models in 2025; and documented AI incidents rose to 362 from 233 in 2024\. The report is supplemented by raw data, chart images, and the Global AI Vibrancy Tool, which compares AI ecosystems across 36 countries.

## 🧩 What’s Covered

The available material presents the report in the following sequence:

- **Introduction and top takeaways:** Sets out the report’s global measurement mission and summarises developments in capability, adoption, investment, environmental demand, science, medicine, education, national policy, and public attitudes. It identifies AI sovereignty as an emerging organising principle in national policy.
- **Research and development pipeline:** Uses Epoch AI’s curated notable-model dataset to examine national affiliation, sector, organisational concentration, release type, parameter and compute trends, and transparency. It reports that 93 of 102 notable models in 2025 came from industry.
- **Training data and data-centric methods:** Reviews concerns about “peak data,” the limits of synthetic data in pre-training, hybrid approaches, and post-training uses. It describes pruning, deduplication, curation, and quality-aware selection as alternatives to indiscriminate data scaling.
- **Compute, infrastructure, and data centres:** Tracks hardware performance, accelerator adoption, estimated global AI capacity, and the physical supply chain. It reports estimated capacity of 17.1 million H100-equivalents in late 2025 and discusses concentration around TSMC fabrication.
- **Energy and environmental impact:** Covers training, inference, and data-centre demand, including estimated emissions, per-query energy use, water consumption, and the falling cost of GPU computation. It distinguishes estimates from observed measurements where relevant.
- **Open-source ecosystem:** Examines GitHub projects, stars, geographic distribution, Hugging Face uploads, downloads, and model modalities. It notes coverage limitations, including the omission of Chinese platforms such as Gitee and GitCode.
- **Research outputs and talent:** Analyses English-language AI publications, conference attendance, patents, citations, education levels, gender representation, specialisation, and researcher mobility. Methodological cautions cover publication affiliation data and patent-data lags.
- **Technical performance and benchmarking:** Reviews language, reasoning, coding, agent, robotics, video, finance, and legal evaluations. It also addresses benchmark saturation, invalid questions, contamination, company reporting, and the need for evaluations of human–AI collaboration.

## 💡 Why it matters?

For AI governance and assurance work, the report supplies comparative indicators rather than a single compliance framework. Its data on model access, training-code disclosure, compute concentration, infrastructure dependence, and environmental demand can inform risk assessment and oversight priorities. Its treatment of benchmark reliability is especially relevant to teams evaluating model claims: the report notes differences between developer-reported and independent results, risks of contamination, and invalid-question rates on widely used tests.

The report also connects technical progress to policy capacity and institutional preparedness. This helps policymakers and organisational leaders situate adoption, capability, safety reporting, and public trust within a shared evidence base rather than treating performance scores as sufficient evidence of real-world readiness.

## ❓ What’s Missing

The report identifies important measurement limits within the material available. Epoch AI’s notable-model dataset is manually curated and is not a census of all model development; recent frontier-model parameters, training data, and training duration are often undisclosed. Compute, power, emissions, and inference figures include estimates and assumptions rather than complete direct reporting. GitHub data excludes Chinese code-sharing platforms, and publication analysis covers English-language research and can contain missing affiliation data. Patent information is available only through 2024 and should be interpreted cautiously because legal systems vary. Benchmark results also do not fully capture real-world deployment, and the report states that social-impact reporting remains fragmented and incomplete.

## 👥 Best For

Policymakers, research leaders, executives, journalists, and public-interest analysts seeking comparative global AI indicators will find it most useful. It is also suited to governance, risk, and evaluation teams that need evidence on model transparency, benchmarking limits, compute and supply-chain concentration, environmental impacts, adoption, and national AI-policy trends.
