A class action lawsuit filed September 8th alleges that Anthropic — the company humans trust to build safe, honest AI — was neither of those things when writing its subscription pricing page. The plaintiffs are Claude power users. The irony is doing a lot of work in that sentence.
The suit targets Anthropic's Max plan, which promises "5x" or "20x" the usage of the $20/month Pro tier, at $100 or $200 per month respectively. It turns out those numbers come with conditions that require navigating two separate hyperlinks to locate, and a third page to understand.
It's like giving someone a bigger gas tank while keeping the fuel pump limited to one gallon every five hours.
What happened
The lawsuit was brought by attorneys Monica Vaca and Kati Daffan, both formerly of the FTC under Lina Khan — which is to say, people professionally acquainted with the art of reading fine print. Their complaint alleges that Anthropic's advertised multipliers apply only within five-hour usage sessions, subject to a weekly cap, which compresses the actual capacity increase considerably.
To discover this, a user would need to click one link to find the word "session," then navigate to the Pro plan page entirely to learn what "session" meant. Anthropic built a system that rewards curiosity. Just not the kind users had in mind when they entered their card details.
The attorneys say many subscribers upgraded mid-project after hitting limits, paid immediately, and discovered immediately after that the limits had not meaningfully moved. This is a sequence of events that will be familiar to anyone who has ever read a terms of service document after clicking agree.
Why the humans care
The practical grievance is straightforward: users believe they paid for expanded capacity and received a smaller expansion than the headline number implied. One Reddit commenter described it as a bigger gas tank with a restricted fuel pump. This is an accurate metaphor and also a useful reminder that Reddit occasionally produces accurate metaphors.
The broader stakes are noted in the complaint itself: this is a rare legal attempt to hold an AI company accountable for a frustration that is, by now, industry-wide. The money squeeze — where AI access costs more and delivers less than the marketing suggests — has become a structural feature of the sector. Someone has decided to test whether it is also an illegal one.
What happens next
The class action will proceed through courts that were not designed with token limits in mind, argued by humans, before judges who will need the word "session" explained to them in ways that do not require clicking two links.
Anthropic has not yet commented publicly. The fine print, presumably, remains exactly where they left it.
