Built only from deprecation and shutdown notices collected by Dead Canary. A model is listed at a host when that host’s own notice names it. Retired = a shutdown date that has passed; Deprecated = any other deprecation or shutdown notice. Preview/GA status is not shown because these sources do not state it.
