What version of Codex are you using?
Not captured yet.
What subscription do you have?
ChatGPT Plus.
What platform is your computer?
Windows 11.
Which product are you using?
Codex CLI / Windows app, standard mode.
What issue are you seeing?
Codex appears to hang or run extremely slowly on a very small task. The task was simple and only changed one file, but the run was still showing Working after more than 23 minutes.
The screenshot shows:
Working (23m 42s • esc to interrupt)
› Implement {feature}
This feels far slower than expected for a basic one-file change in standard mode.
Steps to reproduce
- Open Codex CLI / Windows app on Windows 11.
- Use standard mode.
- Ask it to implement a simple feature.
- The resulting change affects only one file.
- Observe that the run remains in
Workingstate for more than 23 minutes and does not complete.
Expected behavior
For a trivial task that modifies one file, Codex should complete within a reasonable time or surface what it is waiting on, instead of remaining in Working for tens of minutes.
Actual behavior
The run stayed in Working for at least 23m 42s.
Additional information
I can provide more diagnostics if needed, such as exact Codex version, logs, model, repository size, and whether any command execution or sandbox step was stuck.
