Kimi K3 now runs inside Codex through an OAuth proxy and existing subscriptions
dr_cintas · x · 2026-07-21
Kimi K3 can now be used inside Codex through an existing subscription, rather than forcing users to switch tools.
The setup uses opencodex, a local proxy that sits between Codex and more than 40 providers. It supports OAuth login for Kimi, Anthropic, and xAI, auto-refreshes tokens, and exposes K3 in Codex’s model picker with reasoning controls.
The poster’s main point: if you already pay for a model subscription, you can now bring it into the environment where you actually work.
