The question is, will anyone pay enough for Mythos to offset the opportunity cost of offering that much Opus? You don't want to end up in a spot where you don't have enough compute and your service's reliability degrades to an unusable state like xAI.
I feel like there's always a demand for the very best models, even at insane prices. If the opportunity cost is x times opus, maybe few but there will always be companies willing to pay x+1 times opus.
