In terms of API costs they're about right, 10% of weekly usage on a 5x sub is roughly $40 (for Astra). Chinese models cost roughly half as much (and have fewer refusals).

Subs have insane value because large companies cannot use the subscription model. They are loss leaders and are often used for passion projects & startups (where the juicy data is).

Ah and OAI stopped offering the 20x sub as of yesterday.
