What Signals Does the Kimi K3 Teaser Video Reveal?

I noticed an interesting detail: Moonshot AI only flashed a 4-second clip in their video, with the number "3" sandwiched in the middle, and then a bunch of people started guessing this was the K3 model. Even more thought-provoking is that they simultaneously released multiple AI comparison videos but deliberately hid the full name of K3, leaving behind only an anonymous code name "Kivine." This stealthy promotional rhythm doesn't look like a tech launch; it looks more like testing market sentiment.
