AI Briefingcodex: OpenAI Coding Agent Running Directly in the Terminal
openai/codex
About the project
OpenAI's coding agent, Codex CLI, runs directly in the terminal on your local computer. You can perform tasks immediately from a terminal window in your development environment without relying on cloud-based services or installing separate IDE plugins. It supports Mac, Linux, and Windows, and can be installed via npm, Homebrew, or scripts.
Logging in with a ChatGPT account (Plus, Pro, Business, Edu, Enterprise) allows you to use Codex within that plan. Usage via API keys is also supported, but account integration is recommended. It can also be installed as an IDE plugin for existing editors such as VS Code, Cursor, and Windsurf.
It is characterized by operating as an agent in the local environment rather than being a simple code completion tool. Unlike the cloud-based Codex Web, it handles tasks by directly interacting with the developer's local file system and terminal environment. It is released under the Apache-2.0 license and has garnered significant community attention, recording over 112k stars.
