❯ Baseten lets enterprises use Kimi K3 inside Codex, billed against their OpenAI commitments

No new vendor neededUS AI inference platform Baseten announced that OpenAI enterprise customers can use open models hosted by Baseten, including Moonshot AI’s Kimi K3, inside the Codex coding tool or via the Responses API. The charges count against the purchase commitments companies have already made to OpenAI, with no separate vendor procurement process.

A Chinese open model on the purchase orderBaseten’s business is running open models for companies and serving their requests; it began hosting Kimi K3 on the day of its July release. K3 is an open model of about 2.8 trillion parameters with leading coding ability among open models. The deal marks the first time a Chinese open model enters the mainstream billing channel of OpenAI’s enterprise customers.

One fewer gate for procurementWhen large companies adopt a new model, compliance review and procurement often take longer than the technical evaluation. Paying with existing OpenAI credits sidesteps that gate. The irony: the same day, according to Bloomberg, OpenAI accused individuals linked to Moonshot AI of taking part in a distillation campaign to extract its models’ reasoning, even as its platform opens a door for Kimi.
