The full [Kimi K3] model weights will be released by July 27, 2026. Further details on the architecture, training, and evaluations will be released alongside the Kimi K3 technical report.
That's a quickstart page for using the model on the platform not a page about the model. I am skeptical you are correct that it said something about model license earlier.
Not the person you're responding to, just a person who still has the original version of the page open in their browser. Quoting from it:
"Kimi K3 is the first open-source model to reach the 2.8-trillion-parameter scale. It is the latest step in Kimi's continued push of model-scale boundaries: in 9 of the past 12 months, Kimi models have set new records for open-source model scale."
The page has definitely changed.
(I'm not sure why you would be skeptical of somebody recollecting something they probably read only half an hour earlier.)
The K3 marketing popup when I look at the Kimi Code page says "Kimi K3 Open Frontier Model". So, if it's not going to be open, they haven't told the whole team, yet.
