Codex CLI is OpenAI's lightweight terminal-based coding agent that brings AI-assisted development to your shell without requiring a browser or IDE. It reads files, modifies code, and runs shell commands based on your instructions — the agent executes your intent rather than operating autonomously.

For ChatGPT Plus, Pro, Business, Edu, and Enterprise subscribers, the CLI is included as part of the plan. At 103k stars, it's among open-source AI developer tools on GitHub that have 103k stars.
