testingcatalog · x · 2026-10-23
Kimi K3.1 is officially teased: both Moonshot's official account and Arena confirmed the new model is coming. A mystery model codenamed Kibitz appeared on Arena, and testers widely believe it's Kimi K3.1.
Leaked impressions: Kibitz's one-shot JS drawing on code arena is rated top-notch and fast; one user had Kimi K3.1 Pro one-shot a demo website in 15 minutes. Insiders (secondhand, unverified) say it will be a very efficient model. Launch may be days away.
