PHYSIX OBSERVATION

K3.1 Pro's advances on terminal tasks and physical simulation show Kimi is extending from a language model toward a foundation model for embodied intelligence. The API price cut and the Highspeed edition are meant to attract developers, but opaque quota consumption may hurt the experience. If it keeps improving physical understanding, Kimi could build a differentiated edge in the AI Agent race.
