Moonshot teases Kimi K3.1 in a video; the model is not announced

Moonshot's Kimi account posted a 24-second video without a caption. Accounts that quoted it describe the Kimi Code terminal showing "Model: Kimi K3.1" as it writes a procedural 3D scene in Three.js. Moonshot has not announced the model, a release date, pricing or weights.

Earlier signs of the name came from users, not from Moonshot: a kimi-k3-1 model id spotted on Moonshot's API platform in late September, and K3.1 in the Kimi Code model switcher on October 21, according to one account on X.

On October 23 the X account LuminaBench posted a screenshot it says shows a Kimi K3.1 Pro blog page Moonshot was editing, and said a release looked imminent. A second account, AiBattle_, posted a screenshot it says shows the same "Kimi K3.1 Pro" tech blog briefly appearing on the Kimi site, and noted the "Pro" name. These are two accounts' claims; Moonshot has not confirmed the page or the name.
