What are GitHub Copilot CLI and Codex?

GitHub Copilot CLI

GitHub Copilot CLI brings GitHub's Copilot coding agent straight into your terminal. Instead of switching to an editor, you type a request and it can plan the work, edit files, run shell commands, and open pull requests on its own. It connects natively to GitHub, so it can read issues, work with branches, and manage pull requests without extra setup. You can pick from many AI models, including Claude, GPT, and Gemini options, and switch between them as needed. Plan mode lets you review a checklist before any changes happen, while autopilot mode moves faster with fewer stops. Every file change and command needs your approval first, so you stay in control throughout the process.

Codex

Codex is an AI coding agent from OpenAI that can plan, write, test, and fix code with real autonomy. You describe a task in plain language, and Codex works through your project step by step, running commands, checking tests, and preparing changes for you to review.

It started as a tool for software engineers but has grown into a wider work assistant used by analysts, designers, and other non-technical teams too. Codex runs in isolated spaces, so it does not touch your main project files directly.

You can use it from a desktop app, a command line tool, inside your code editor, or through ChatGPT on the web, and everything stays in sync across each place you work.
