Kimi 发布开源旗舰模型 K3.1 Pro：2.8T 参数、100万 Token 上下文，实测 3D 与视频动效

Moonshot AI released its flagship model Kimi K3.1 Pro, with 2.8T parameters and a 1M-token context window. Full model weights are expected to open up by November 4. API pricing is 13 yuan per million input tokens and 68 yuan per million output tokens, roughly half of K3. A Highspeed version outputs about 2 to 3 times faster at double the price.

Why it matters: Moonshot AI roughly halved Kimi K3.1 Pro's API price against K3, while the Highspeed version trades double the price for about 2 to 3 times the output speed.
