What version of Codex is running?
custom build, slightly modified from 0.80 tag
What subscription do you have?
ChatGPT Pro
Which model were you using?
gpt-5.2-codex
What platform is your computer?
MacOS 26.2
What issue are you seeing?
I was coming up on the end of a 5-hour window, and suddenly Codex gave me 429 rate limit errors. The usage display inside Codex and also on the ChatGPT website both said I had about 61% usage remaining in my 5-hour window, which felt about right given my usage patterns for the past 5 hours.
Every time I tried a command, the "retry after" was about 60 seconds.
This issue lasted about 15 minutes, starting around 11:30 PM PST January 12, until the 5-hour window reset and things started working again.
What steps can reproduce the bug?
I don't think it will help much but here's one sample output from when it was failing.
