Do you know where these rumors are coming from? I keep seeing posts like yours on HN and Reddit, which, yes, literally confirms there are rumors, but I can't tell whether they're based on anything.
All their API routes for non existing models return 404 and when there's a new model it returns 403.
I follow Leo for the rumors, he has been pretty accurate but again they are rumors so nothing is guaranteed. I don't know his sources.
