Editorial summary

Stanford HAI's flagship annual benchmarking report — nine chapters covering research output, technical performance, responsible AI, economics, science, medicine, education, policy and public opinion. The 2026 edition documents global generative-AI adoption gains, US private AI investment totals, and a drop in the Foundation Model Transparency Index.

Why this matters

The Stanford HAI AI Index is the closest the field has to an annual census. Its nine chapters cover research output, technical performance, responsible AI, economics, science, medicine, education, policy, and public opinion — and most of the headline statistics you see in news coverage about AI trends are lifted from this report. The 2026 edition documents continued global generative-AI adoption, shifting US private-AI investment totals, and a drop in the Foundation Model Transparency Index. If you want to check whether a claim you just read about AI is backed by real data, this is normally the fastest place to verify or falsify it.
