Mythos/Fable release was significantly delayed because Dario is pushing for regulatory capture.
It also plays into the hype because there was no one else releasing a model better than Opus. The same thing was with the scarcity crap. They said Fable will not run on subscription, then they will run just for a little while and then forever... Once you get the game they are playing it starts to become quite laughable. If you check his history he was doing the safety/terminator stuff since the days at OpenAI when the models couldnt even calculate 1+1 reliably
Is there any actual proof of this? Everything suggests it's a sincerely held belief and there's been no whistleblowers claiming otherwise. "Since before they could add 1+1" works against your argument because the models had no commercial value, no guarantee they would ever have commercial value, and plotting regulatory capture was about as serious an idea as regulatory capture of antimatter engines.
All three models were quite likely undergoing training at the same time, with Ant a couple of months ahead. Glasswing was announced 3 months ago, Sol and Kimi were already being trained at that point. They are taking snapshots and doing experiments the whole way through anyway and all models will continue to be trained after release. Kimi 3.1 could be better than Fable 5.1
