Kimi K3 is now available to enterprise users through OpenAI’s Codex coding tool via U.S. AI infrastructure company Baseten. Usage fees are charged directly against customers’ existing OpenAI purchasing commitments, eliminating the need for a new supplier procurement process. The arrangement places Kimi K3 in OpenAI enterprise customers’ established paid billing channel and marks the first time a Chinese open-source model has entered this enterprise procurement system.
