>OpenAI will not implement new architectural changes unless they've tested the changes themselves internally.

OpenAI validating it can still happen faster than they can get the compute to serve the models themselves[1]. It doesn't make a lot of sense to give out details if they want to be a serious contender or even as some have said, be acquired.

Yeah there's noise but if they have the real deal then it doesn't matter. They only thing they need to do is let people pay to use the models.

[1] I'm assuming this is the primary cause of the delay. That may not be the case of course.
