kimi k3.1

Kimi K3.1 refers to Moonshot AI’s Kimi K3.1 Pro, the first model in the K3.1 series and its most capable flagship model to date.[1][3] Sources describe it as a 3T-class open-weight, multimodal model with a 1M-token context window, aimed at coding, 3D creation, financial research, and agentic workflows.[3][14]

The public sources consistently establish the model identity, positioning, and core capabilities, but they vary on parameter details, with some citing 3T-class wording and others giving 2.8T total / 104B active parameters.[3][10][22][26] Pricing information is not clearly established in the primary Moonshot documentation provided here; one secondary source claims standard API pricing of $2 per million input tokens and $10 per million output tokens, while a faster Highspeed version is said to cost 2x the standard model.[19][23]
