I went down the rabbit hole: Anthropic is already being sued over exactly this. And the $200 plan really only provides only around 2x the weekly usage of the $100 plan

Here is where the confusion comes from.

Anthropic’s pricing page says: “Choose 5x or 20x more usage than Pro.”

That naturally makes the $200 Max 20x plan sound like it includes four times the usage of the $100 Max 5x plan.

Only further down does Anthropic clarify: “Max gives you 5x or 20x more usage per 5-hour session than Pro.”

Those multipliers do not apply to the separate weekly caps, whose exact size Anthropic does not disclose.

A proposed class action filed in June alleges that Max 5x delivers around 3.5x Pro’s weekly usage, while Max 20x delivers just 6–8x. In practice, the $200 plan therefore provides only around 2x the weekly usage of the $100 plan, sometimes even less depending on the model.

The “20x” is real within each five-hour window. The weekly limit makes the overall offer look very different.

h/t @Hesamation for finding the original court files first i think
