What changed

Moonshot describes Kimi K3 as an open-weight multimodal model built for long-horizon tasks. Its model card identifies 2.8 trillion total parameters and a dedicated Kimi K3 license.

The everyday takeaway

Check the license, full model size, and compatible infrastructure before you think about a download. “Active parameters” and total stored parameters are different measurements. An efficient architecture can reduce computation while the complete checkpoint still needs substantial storage and memory. Hosted access may be the practical route for many readers.

What we have verified

The official model card documents K3 and its license. Kimi’s help center identifies July 27 as the full-weight availability date. We have not run this model.
