Upgrading plans is the absolute prerogative of the user. You do not need to upgrade if you are currently satisfied with your plan. Token allotment replenishes every billing cycle. However, we recommend that users assess how they intend to use the AI plans. If a regular user, the current plan they are subscribed to would sustain them until the next billing cycle. However, if assessed as a power user on a daily basis, we strongly recommend upgrading to either the Pro plan (1 million tokens) or the Pro Max plan (unlimited tokens).
