Stanford Institute for Human-Centered Artificial Intelligence (HAI) — Headquarters: Stanford, California

Note: While the source URL is from hai.stanford.edu and the additional context states the institute is 'Located on the Stanford University campus', the actual source text excerpt provided does not contain any information about the headquarters location. The excerpt only shows an 'About' heading with no body text. Without the actual content of the About page, the claim cannot be verified against the source material itself, even though the URL domain and context strongly suggest Stanford, California would be confirmed if the full text were available.
