looking at the other replies I'm not seeing what I consider the most important rebuttal to this argument: there is no real "adopting" in this hybrid open/close space right now, the lock-in is minimal and as much as different corporations are trying to create a lock-in effect by closing down their tools and interfaces, they are not really succeeding
I can constantly jump from one provider to another, and to my local servers which are already able to run very useful models at reasonable hardware cost, and I intend to continue doing that for the foreseeable future
the one thing I'm not going to do is tying my tooling to one provider or another or getting overtly used to the specifics of a model outside of my control
more than the weights or the training, which of course are very important, the real battle right now is for establishing some dependency mechanism so that your users won't just flee en-masse as soon as you inevitably try to abuse your market dominance and lock-in mechanisms, as is customary in everything computing these days - note that i don't explicitly talk about raking up prices, that is just one of the most difficult methods as people are very sensitive to that, when you can sneakily sell user data, get government contracts from never-disclosed conditions, or even just incorporate your intelligence to ad networks in one way or another
