Kimi K3.1 Pro rolls out on web and mobile after mystery model Kibitz wows Arena testers with one-shot builds

Moonshot's Kimi K3.1 Pro is now rolling out on Kimi AI web and mobile, positioned as the all-around flagship for complex and professional work. A mystery model called Kibitz appeared on Arena ahead of launch, widely believed to be Kimi K3.1, with official teasers from both Kimi and Arena.
Early community tests focus on coding: Chetaslua showed top-notch one-shot JS drawing from Kibitz, and K3.1 Pro built a demo website in 15 minutes in one shot. Secondhand word from "friends inside Kimi" suggests it will be a very efficient model (unverified).
