A new model named Kivine, potentially an upcoming Kimi K3 model from Moonshot AI, was observed on the Arena platform, with a user catching a comparison against Fable 5 in a Universe simulation prompt. The Kimi K3 model demonstrated more complex and visually appealing features, including a first-person POV planet spin at x100 speed, while Fable 5 was faster and had more robust UX components.
