It's just a highly unoptimized space. There is very little market consolidation at this point, everyone is trying things out that lead to wildly different outcomes and processes and costs, even though in the end it's always just a bunch of utf-8 characters. o3 was probably just super expensive to run, and now, apparently, it's not anymore and can beat sonnet/opus 4 on pricing. It's fairly wild.
