> Kimi K3.1 Pro is an open-weight

Lie right in the first sentence

How so? The weights are up on HF.

Look at the license. It has all sorts of arbitrary restrictions, so it's not an open weight model, in the same way that "source available" is not open source (but worse, since there's nothing human readable in the weights).

Maybe, but nothing happens if you ignore it and use it however you want. Who and how will check it? More like a pinky promise

"I can just break the law" isn't exactly how you get "open" though

It's very likely (though no precedent yet) that model weights aren't copyrightable under US law since they don't meet basic authorship and originality requirements. Therefore the only thing protecting the weights is the contract you sign in order to download them, which is much weaker than copyright. Beyond a cease and desist, the lab would be hard pressed to prevent you from doing whatever you want with the weights. Not a lawyer though.

The weights are fully available. Everything else is just a suggestion at this point. Seems open enough to me.

I don't think there were any court cases about violating open weights licenses, nor there will be.
