It's weird on the surface, sure, but only on the absolute surface. Apple has never taken model development seriously and aside from a bit of a fuck about with apple intelligence (which they clearly didn't invest a lot in), it's always been pretty clear that they were positioning themselves to be a user and not a developer, which will probably prove to be the smartest approach in the end with most of the developers bankrupt and the models that survive commodified.
Shit, Apple will probably be able to turn around in a few years and buy one of these burnt out tech startups with a decent model for a small fraction of what it would have cost for them to build it themselves.
