Suspected Kimi K3 Spotted in the Arena
testingcatalog · x · 2026-07-15
A new model named Kivine has appeared on @arena, which is highly likely an early version of Moonshot/Kimi K3.
The author shares some comparative observations:
- In a Universe simulation prompt, Fable 5 finishes faster and has more stable UI components.
- Kimi K3 delivers a more complex output that is visually more engaging.
- During certain interactions, like selecting a planet and cranking the speed to x100, the model generates an exaggerated first-person rotation effect.
Overall verdict: the two are very close in capability, but they differ in terms of interaction stability and visual complexity.
