The plan allows 550,000 credits per 5 hours and 5,000,000 credits per week.
The plan allows 0.6 times the allowance of SuperGrok per week.
A ceiling is what the plan allows, not what you will use. If you write code an hour a day, neither plan's cap is the thing that decides this and the cheaper one wins by default. The multiple matters when you are the kind of user who hits limits.
Prices and caps here change without notice, which is why this page is regenerated from the catalogue on every deploy rather than written once. Compare the raw entries at claude-pro and x-premium-plus.
