When should I redeem a Codex banked reset?

Only when your weekly gauge is at 100% and you have heavy work ready to run right away. Redeeming earlier throws away the rest of the current window, and a slow window is more exposed to a global reset.

Does a global reset refund a banked reset?

In our case it did not. We redeemed a banked reset, used 14% of it, and a global reset 12 hours later gave a fresh window without crediting back the unused 86%.

How often does OpenAI reset Codex limits?

Public trackers logged 59 resets from September 2025 to October 8, 2026. Since August 1, 2026 the median gap has been 3.0 days.

What is the chance of a Codex global reset in the next 24 hours?

At the August to October 2026 pace, about 25%. It is a rough estimate: OpenAI does not schedule resets and the pace has changed a lot over time.

Never redeem a Codex banked reset before reading this: the global-reset math

On October 2, 2026 we hit 100% of our Codex weekly limit at 08:48 UTC and redeemed a banked reset a minute later. At 21:10, with 14% of the new window used, OpenAI pushed a global reset to every account. We got a fresh window, but the 86% we had not used of the banked one was simply gone: about $150 of API-priced Codex. Here is how to avoid doing the same.

Public resets since Aug 1, 2026: 20, one every 3.4 days on average.
Chance of another one within 24 hours: about 25%. Within 48 hours: 44%.
The rule: redeem only when you are blocked, and only when you will use the window fast.

How banked and global resets work

A global reset zeroes the Codex gauge for every account at once, usually with a post from OpenAI and no warning. A banked reset is a refill OpenAI grants into your account to redeem when you choose. According to OpenAI's help center, redeeming one refreshes your Codex usage windows and moves your weekly reset date. In our case, a later global reset did not credit back the unused part of a redeemed banked reset.

OpenAI resets Codex more often than you think

Public Codex usage resets per month, Sep 2025 to Oct 8, 2026 (codex-resets.com)

The tracker at codex-resets.com logs 59 public resets from September 2025 to October 8, 2026. The pace has changed a lot. Early on there were months with none, and one gap of 67 days. Since July, resets have come every few days: the median gap since August 1 is 3.0 days. The full list with gaps is in codex-reset-history.csv.

The odds, worked out

Treat resets as random arrivals at the recent pace: 20 resets in 68 days is a rate of 0.29 a day. The chance at least one lands within h hours is 1 - e^{-0.29 × h/24}.

Chance another public reset lands within the next N hours, at the Aug to Oct 2026 pace

Now apply it to a banked reset. Our full Pro $100 windows took a median of about 25 hours to burn. Redeem a banked reset and there is roughly a 26% chance a global reset lands before you finish it. On average it lands halfway through, so the expected loss is about 15% of a window, or $27 at our $175 median. That is the price of redeeming early. Redeeming while your gauge is not yet full is far worse: redeem at 60% and you throw away 40% for certain.

Your situation	What to do
Gauge under 100%	Do not redeem. You lose whatever is left.
Blocked, natural reset in under a day	Wait if you can. A global reset in that time is about 25% likely and costs you nothing.
Blocked, natural reset days away, heavy work queued	Redeem, and start the heaviest work right away so the window burns fast.
Blocked, light work only	Hold. A slow window has the most exposure to a global reset.
A model launch or outage was just announced	Hold. Launch days have repeatedly come with resets, such as September 5 and September 22.

Check before you redeem

Look at a public tracker such as codex-resets.com for the last reset date and any announcements.
Run /status in Codex to see your gauge and when your weekly window resets on its own.
Decide how fast you will use the new window. Fast is safe; slow is a bet.
