codex - 💡(How to fix) Fix Duplicated output [4 comments, 4 participants]

TL;DR

The issue of duplicated output in Codex CLI 0.121.0 with the gpt-5.4-xhigh model on Ubuntu may require adjusting the model or CLI settings to prevent duplication.

Guidance

• Verify Model Settings: Check if the gpt-5.4-xhigh model has any specific settings or configurations that could be causing the output duplication.
• Check CLI Options: Look into the Codex CLI documentation for any options or flags that might control or affect output behavior, potentially preventing duplication.
• Test with Different Model: Try using a different model with the Codex CLI to see if the issue persists, which could help determine if the problem is model-specific.

Notes

The provided information lacks specific details about the expected behavior and additional context, making it challenging to provide a precise solution. The issue might be related to how the model processes input or an undocumented feature of the CLI.

Recommendation

Apply workaround: Given the lack of detailed information and the specificity of the issue to the gpt-5.4-xhigh model, attempting to adjust model settings or using a different model as a workaround seems like the most viable next step.
