Codex
OpenAI's coding agent — terminal, IDE, cloud and GitHub
Descripción General
Codex is OpenAI's agentic coding system: it plans and executes multi-step engineering tasks, runs in your terminal or IDE, executes in sandboxed cloud environments, and reviews or fixes GitHub issues autonomously. Included with ChatGPT plans (token-based usage since April 2026), it became one of the two dominant coding agents alongside Claude Code.
