I suspect this is why OpenAI is going more in the direction of optimising for price / latency / whatever with 4o-mini and whatnot. Presumably they found out long before the rest of us did that models can't really get all that much better than what we're approaching now, and once you're there the only thing you can compete on is how many parameters it takes and how cheaply you can serve that to users.
