Which model powers each AI engine?

The AI engines your customers ask change models constantly, and most of them never say which one wrote a given answer. Here’s what each runs today, how it picks its model, and a dated history of every change — with the primary source for each.

Where we read the model from the engine’s own answers, it’s markedObserved. Where only the vendor discloses a default, it’s Vendor-stated — we never dress one up as the other.
