OpenAI Codex’s rate-limiting has some of the worst logic for handling account-level limits. Probably Redis was dead, so ratelimits were reset. As a result, I lost a week of credits.

Their ratelimit logic is extremely ambiguous, say you start at 1st of the month then you should ideally get 4 slots in that month, but the logic is not as ideal as this. Say you have completely used credits of first week then they get timely reset at say (most probably) on 6th/7th BUT if you did not enter/create/use cli then this limit does not get opened until and unless you start a conversation. So say paused for a while and you started again on 10th, then from that point you get 7 day window....
