Research University and AI Research
Stanford University provides undergraduate and graduate education and conducts research across seven schools, including engineering, medicine, business, and the humanities. Its offerings extend to online courses for the public and executive and policy education through the Stanford Institute for Human-Centered AI (HAI). HAI funds research, trains early-career scholars, and produces the annual AI Index, connecting technical work with questions about AI’s economic and societal effects.
Founded in 1885 by Leland Stanford and Jane Lathrop Stanford, the university opened in 1891 and is now led by President Jonathan Levin. Its AI research includes FlashAttention, an algorithm that accelerates Transformer attention without approximation. By computing in blocks and avoiding large intermediate matrices in GPU memory, it reduces memory traffic and makes attention more efficient for model training and inference.
Stanford reported enrollment of 7,289 undergraduates and 10,025 graduate students in autumn 2025. Its funding includes student income, sponsored research, endowment income, gifts, and health care services. In 2026, Stanford announced that Stanford HAI and Stanford Data Science would combine under the HAI name, led by James Landay. The planned structure brings together HAI’s research and policy network with Data Science’s Marlowe computing cluster and fellowship program, linking computational resources with research across disciplines.

Start with the essay based on Yegor Denisov-Blanch's talk to understand why commit and pull-request counts can mislead, and how expert assessments inform an alternative measurement method.

Use this talk to learn how historical Git data, matched teams, and models trained on expert code assessments contribute to an AI ROI evaluation framework.

The World's Fair talk presents stronger gains for simpler tasks and greenfield development, while some complex enterprise tasks show negative effects. The causes of those decreases remain unresolved.
The Code talk argues that codebase cleanliness and how teams use AI matter more than token consumption. It recommends pairing engineering outcomes with guardrail metrics to account for technical debt and rejected output.
