Not sure what you are promoting here. The "open" model currently seems to work, if you a) burn outsized amounts of money that you have in the bank, in an attempt to get good eventually (Meta) or b) distill other models.

Both ask for a fairly narrow definition of what constitutes a good idea. There is plenty indication that both Meta and all of the Chinese labs will go closed, as soon as that path makes more economical sense for them. They are certainly already steering in that direction.
