Open weights just caught up with the closed frontier, for building and for defending!

Kimi K3.1 Pro and Kimi K3.1 Pro Ultraspeed are both live on the Routstr network.

Building: #4 in Artificial Analysis Intelligence Index. #2 in Terminal Bench 4.0, only behind Opus 5.5.

Cyber Defense: #2 in AA Cyber Index, but #1 among publicly available models.

And it doesn't refuse the work.

Try them, model: kimi-k3.1-pro / kimi-k3.1-pro-ultraspeed

Happy building and defending.
