Citewake Model Register
The Model Register

1The baseline
Where every change is measured from: the models on each maker's list, the model each AI's answers reported, and how it answered in the latest published edition (28 October 2026).

Per answer, from the edition's answers. ± is normal variation: the largest movement between two editions one day apart on the same models. A change must exceed it to count.
How much does an answer change on its own?
The same question asked of the same AI in one edition and the next, on the same model (90% intervals).
