What variant of Codex are you using?

CLI

What feature would you like to see?

It would be nice to provide a feature where Codex can automatically switch the reasoning level of the model being used based on the complexity of the task it's currently executing. The model is entirely capable of determining the best reasoning level for the task (or sub-task) at hand; it should be provided with a tool to automatically switch reasoning level based on its judgement.

TL;DR

Implementing an automatic reasoning level switching feature in Codex may require modifying the model's configuration or integrating a custom decision-making module.

Guidance

  • Investigate the Codex CLI documentation to see if there are any existing parameters or flags that can be used to adjust the reasoning level based on task complexity.
  • Consider developing a custom script or wrapper around the Codex CLI to dynamically adjust the reasoning level based on the model's output or task characteristics.
  • Evaluate the feasibility of integrating a machine learning-based decision-making module that can analyze task complexity and adjust the reasoning level accordingly.

Notes

The implementation details of the automatic reasoning level switching feature are unclear and may require further research and experimentation to determine the best approach.

Recommendation

Apply workaround: Implement a custom script or wrapper around the Codex CLI to dynamically adjust the reasoning level based on the model's output or task characteristics, as this approach seems more feasible given the current information.
