Explanation of the task elapsed time mechanism
A typical Codex task takes 1-30 minutes to complete, with delays coming mainly from:
- Environment initialization: Preparatory work such as cloning warehouses, installing dependencies, etc. (approx. 1-5 minutes)
- Iterative validation: Multiple cycles of test-modify (complex features may require 10+ attempts)
- Audit record generation: Organize terminal logs, test reports and other verification materials
Compared to ChatGPT's instant response, Codex essentially simulates the complete workflow of a human developer: understanding requirements → writing code → running tests → fixing problems → submitting changes. For example, to fix a cross-file reference bug, Codex needs to 1) analyze the call chain 2) modify the related files 3) execute impact tests 4) deal with side effects, and this in-depth processing capability is exactly where its value lies.
