How do you decide which AI engines to cover?
We cover 8 engines, and an engine joins that set only when we can measure it faithfully and describe how. That means a collection path we trust, a provenance label we can publish, and a confidence signal for your market. Engines we cannot yet measure this way stay off the list with the reason stated publicly.
Coverage counts are the easiest number in this category to inflate, because nobody checks how a given engine was actually sampled.
Our list is derived from the registry the product itself runs on, so the number on this page and the number in your dashboard cannot drift apart.
When an engine is held back, we publish why rather than leaving a gap for a competitor to explain on our behalf.
