OpenAI Codex CLI - Frontier reasoning in the terminal

For developers who live in the terminal and want ChatGPT‑level reasoning plus the power to actually run code, manipulate files, and iterate – all under version control. In short, it’s chat‑driven development that understands and executes your repo.

OpenAI's answer to Claude Code.


Not be confused with Codex CLI by Microsoft, nor OpenAI Codex, which was launched in 2021!

I thought it would be a code editor like Cursor.

This sounds like a seriously powerful tool for devs who live in the terminal. Combining ChatGPT-level reasoning with real execution, file manipulation, and version control could really streamline workflows. Excited to see how this evolves for hands-on coding environments!
