When does Codex reset? Weekly limits and moving reset dates
Codex reset times aren't fixed — they move. Here's how the weekly Codex/ChatGPT limits work, why the dates drift, and how to see your exact reset.
One of the most confusing things about Codex is that the reset date moves. Unlike a clean weekly clock, Codex resets land on a rolling window that can feel unpredictable — so people keep re-checking, hoping it's back.
How Codex resets actually work
Codex usage is metered on a rolling weekly window tied to when you spent it, not a fixed calendar day. Because your heavy days shift week to week, the effective reset drifts — which is why it rarely lands at the same time twice.
The separate model buckets
There are distinct buckets for standard models and the heavier GPT-5.x-Codex models, and they can reset independently — so 'all models' can look fine while the Codex bucket is empty.
See your exact reset
Instead of guessing, How Much Codex shows a live countdown to each bucket's reset for every connected account — no more refreshing to check.
