Indices

Weekly series on how AI models cite sources. Each edition stays published on its own page, and changes are only flagged when they pass the statistical test.

Source: data observed and catalogued by First Answer. Each week, we measure by model the share of answers that cite the index's domain among their sources and compare it with the previous week. A change is flagged as significant only when it exceeds the 95% margin and is at least 1 pp. Weeks with a smaller-than-usual base are flagged and left out of the comparison.
