Built for developers and technical teams that want to delegate larger tasks, from targeted code changes to substantial parts of the application-development lifecycle. You can describe a task in plain language and point it at an existing project or a new development goal. Codex can work across parallel sessions, edit files, run commands and tests, and return results for review. It is available through a desktop app, IDE, terminal, cloud and supported mobile access through ChatGPT.
