Leak: Moonshot's Kimi flagship 'x4' done with pre-training, K3.1 in internal testing

Leaker Lentils80 reports that Moonshot's next flagship model, internally codenamed "x4", has finished pre-training and is in mid-to-late post-training, with core capabilities still being trained — so don't expect the next major Kimi model very soon.
lyraxana adds that Moonshot has started testing Kimi K3.1 internally. Both claims are unconfirmed by the company.
