Why does this issue persist? Hasn't anyone noticed it? Even in version v0.138, Compact is still broken.

The Codex desktop client hasn't appeared since this week (latest version). If you're using an earlier version, i recommend switching to the 5.4 mini model and then compacting it.
macOS too.

Yes, that's a valuable suggestion. However, the CLI still has a bug (even in the latest v0.139) when running long-duration tasks with the 5.5 model. We can't reasonably expect developers to switch models manually as a workaround, especially when they're building automated workflows. Therefore, I believe this remains a serious bug and severely impacts the user experience.

yes，when we are working this is a problem，especially in the /goal mode.Switch model just could use when the session is end or compact broken

Thanks for reporting this problem. Until recently, Codex used a separate endpoint and server-side logic for compaction. We recently switched to a more robust approach where the compaction logic is moved locally using the same endpoint as normal turns. This eliminates "remote compaction" errors and increases the stability and reliability of compaction operations. If you see further problems with compaction, please use /feedback and open a new bug report.
