Using Codex with your ChatGPT plan
Source: OpenAI Help Center Topic: Current operational overview of Codex surfaces, cloud delegation, code review, plugins, and workspace controls.
1. Codex is presented as one system across many surfaces
OpenAI describes Codex as usable from the CLI, IDE, web, app, SDK, and even Slack. The app specifically highlights parallel agents, built-in worktrees, skills, automations, and git support.
2. Background work runs in isolated sandboxes
The help center says Codex can be delegated work in the cloud, where each task runs in an isolated sandbox with the repository and environment available. Results are meant to be reviewed, merged, or pulled back down locally.
3. Code review is now a first-class product workflow
OpenAI documents automatic GitHub review for personal pull requests and team repositories. This is an important evolution: Codex is not only described as a coding worker but also as a persistent reviewer.
4. Plugins are distribution units with admin controls
Plugins package reusable workflows as a combination of skills, optional app integrations, and MCP configuration. Workspace admins can control plugin availability and actions, and these controls apply across Codex-related surfaces rather than only in one client.
