Codex Configuration Guide

Codex CLI is an open-source local programming agent launched by OpenAI. It can read code, modify files, run commands, and assist with development tasks within the terminal. Through the Ace Data Cloud proxy, you can use Codex CLI at a lower cost without subscribing to an official OpenAI account separately.

Choose the appropriate complete configuration tutorial based on your usage scenario:

Platform	Description	Tutorial Link
VS Code	Official extension, enables chat, reference files, and preview diff in the editor sidebar	VS Code Configuration Tutorial
Terminal (CLI)	Core experience, start by running codex in any terminal	Terminal Configuration Tutorial

Tip: For the first application, you can go to the Ace Data Cloud Console to obtain an API Token, which grants free credits. Codex CLI works through Ace Data Cloud's OpenAI Responses compatible interface (/v1/responses). For more models and billing information, refer to the OpenAI Service Page.
