Suppose you enter a casino and the owner welcomes you in and sees that you are a frequent loyal s̶p̶e̶n̶d̶e̶r̶ customer (with the amount of tokens you are spending a month) with an existing membership.
With this new VIP membership that comes with 5x or 20x usage, if you spend $100 you get 5x. $200 you get 20x and you get to spin the wheel and use the slot machines unlimited times even at peak hours more than most without any restrictions, 24/7, no waiting for hours with priority.
So spend more to get more abundance and more simultaneous spins at the wheel.
Except if you're trying to abuse the slot machines themselves or sharing or reselling your membership to other customers who want a spin at the roulette wheel; but were previously banned. [0]
Both Pro plans include the same core capabilities. The main difference is usage allowance: Pro $100 unlocks 5x higher usage than Plus (and 10x Codex usage vs. Plus for a limited time), while Pro $200 unlocks 20x usage than Plus.
So curious that the cost in the comparison is just a flat $100, not "$100 or $200" and yet the usage has the "or". Surely just a lapse in copy editing.
Anthropic is the exact same way, I think they're just trying to avoid having 5 different subscription tiers visible. Probably needing 20x is very niche
