We are also sort of at a "bespoke factory" stage where building a factory means doing it around your specific codebase, each of which has their own needs and quirks. Just taking one of these wholesale from one company and using it at another would not work.

We'll see if in the future, as people begin software projects this way, if there is more standardization. I suspect that there's just too much going on too fast at the moment to do it any other way, a decent factory for Opus 4.8 looks very different than one good for Astra, I'd guess. And models are just one axis.
