Codex Router

External-model router for Codex and DeepSeek Harness with Kimi and Grok support.

Open source

Description

A credential-isolating local router that allows users to integrate external AI models—including Anthropic, Kimi, DeepSeek, and Grok—directly into the Codex App and CLI. The integration merges external entries into Codex's native catalog, enabling routed models to appear in the standard picker alongside native GPT models. It includes a background service, gateway, and provider credential management.

Install the router from this public repository:
https://github.com/duolahypercho/codex-router

Follow AGENTS.md. Preserve my existing Codex models, profiles, settings, and
ChatGPT login. Use only the provider authentication I choose, safely migrate
only recognized older versions, run the Codex doctor, and leave the final app
restart to me. Never ask me to paste a token or API key into chat.
