OpenAI Codex
Lightweight coding agent that runs in your terminal
OpenAI Codex is an AI-powered software engineering agent designed to translate natural language instructions into code, fix bugs, run tests, and propose pull requests—either through ChatGPT or via the open-source Codex CLI for local terminal-driven coding tasks. Each task runs in a sandboxed environment, preserving security while understanding and modifying your codebase autonomously.
