All those models are only as good as the data they’re trained on. Google and Meta both have the most relevant proprietary data that cannot be rivaled. Not even close.
This is easily illustrated by ChatGPT not being Google or Meta and doing a pretty great job with available sources.
So no, this doesn’t matter much, imo.
Having seen the average level of discourse on Facebook, I have no reason to believe that it contains any proprietary data worth training on.
