When does Grok's weekly limit reset?
Once a week, on each account's own schedule. Your date and time are in Grok under Settings → Usage.
Full answer and how it works
The weekly limit for paid Grok users resets once a week, but the time differs for each account. Your next reset date and time are shown under Settings → Usage on the Grok website or mobile app, along with how much you've used this week and a breakdown by product.
When the weekly limit runs out, paid features pause until the next reset; free Chat and Voice keep working and reset on their own schedule. To keep going right away, buy Extra Usage Credits on the web or upgrade to a plan with a higher limit.
xAI also occasionally resets limits early for all users. So far each one has come with a new version or feature launch. Every one is listed in the Grok reset history.
