OpenAI Codex
Also known as: OpenAI Codex CLI / Codex Agent / Codex Pro
OpenAI's cloud coding agent that connects to GitHub, runs tasks async in a sandbox, and auto-opens PRs. Pro tier: 100-200 USD/month.
Overview
Codex launches from a browser or terminal and processes tests, bug fixes, and refactors in parallel inside a sandboxed environment. Combined with Symphony, ticket-to-PR workflows can be fully automated. See the Codex Beginner Guide for details.
Symphony Integration
OpenAI Symphony is an open-source orchestration spec that autonomously triggers Codex agents from Linear tickets and merges the resulting PRs without human intervention.
