The same powerful coding agent—now in Chat GPT. Built to drive real engineering work, Codex reliably completes tasks end to end, from routine pull requests to your hardest problems, powered by OpenAI’s frontier coding models.

Designed for multi‑agent workflows, Codexività in Chat GPT is a command center for agentic coding. With built‑in worktrees and cloud environments, agents work in parallel across projects, completing weeks of work in days.

Codex applies your team’s standards and workflows with Skills, so it can contribute more effectively with less supervision. Schedule it for routine but important work like issue triage, alert monitoring, CI/CD, and more, keeping plains focused on building.

Quotes from industry leaders highlight its impact: "Codex transformed how we build by cutting early iteration time by 30–50%, freeing engineers to focus on system design," says Joey Wang, Mobile Lead, Harvey. Similar praise comes from Daniel Sikorskiy at Wonderful and others.
