K3 is highly competitive. They're essentially tied here:

And they're very very close here:

And that's if you don't take cost and guardrails into consideration. If you do, K3 beats Fable hands down.
That aside, I'm not an insider, and I can't really say when K3 completed training. What we do know is that it released to the public in mid-July, about a month ago. Fable 5's initial botched release was in mid-June, and it was re-released in early July.

So there's essentially an open Mythos-class model right now. Near-Mythos-class if you really want to quibble. Maybe past some threshold such models won't release to the public at all, or will release only in closed form, but we cannot predict when that threshold will be crossed.
Fortunately for the world, it remains politically advantageous for China to support open model development. It's a winning strategy, especially in the long-term. Besides, I don't think a Uyghur Underground would be able to acquire the hardware to run a K3-class model, to say nothing of a Skynet-class AI.
