i guess the idea here is that if the end user cannot discriminate based on capability above some threshold, the premium that you can charge for more capable models either disappears entirely (if the end user is the principal source of truth on quality) or gets arbitraged down (if the end user is merely an agent of the principal source of truth on quality). to maintain that premium in perpetuity, you just need (a) trusted benchmarking services that can distinguish between premium and generic, and then (b) a way to prove to the end user that a given output is premium.

so this solves for (b).
