The gap depends heavily on which models you're comparing and through which channel. We track normalized pricing across 2,614 inference SKUs and 47 vendors and the spread between cheapest and most expensive option for functionally similar models regularly exceeds 30x. Direct from model developer vs third-party platform alone averages 7x on input tokens. The frontier model vs budget model gap adds another layer on top of that. The 37x figure is plausible depending on the exact comparison. Full data at a7om.com if useful.
