I guess being Chinese company they decided to skip version 4, while also giving impression to be on the similar iteration with leading companies (claude opus 5). I wonder if other Chinese labs like Kimi/Moonshot will follow suit.

  Moonshot has already teased K3.1 so not likely

    K3.1 would likely be a deeper/longer post-train from K3, so that’d make sense.
    It’s all marketing anyways, but that’s at least how a lot of labs have been naming things (sometimes).
