Weaknesses
- -Meaningful use requires a paid ChatGPT subscription such as Plus, Pro, Business, or Enterprise, since access on the Free and Go tiers is very limited.
- -The cloud sandbox runs with internet access disabled during task execution by default, so any task that needs to install dependencies or call external APIs requires you to manually configure domain allowlists and permitted HTTP methods per environment.
- -Codex executes autonomously in isolated containers and hands back a finished pull request, so you cannot steer or correct it mid-task the way you can with interactive assistants like Cursor; you only review the changes after the run completes.
- -The Codex CLI assumes a Unix-style environment, so Windows users must run it through WSL2 rather than natively, adding setup friction.
