11 days is a long time. It does not take that long to implement inference at providers. In my opinion, seems like they're being pre-emptively cautious about government intervention/review
I believe Kimi also does some sort of Q&A and eval for day 0 partners, since early on a long of inference providers just weren’t running their models properly.
Now that they have compute capacity to train larger models, there is a non-zero chance they will be in the lead by next year.
In which case they will probably stop sharing to protect their position.
Which basically translates too "Don't give away tools that can be used to undermine your own goals".
