A paying customer, Karl Kahn of Washington, D.C., has filed a lawsuit against Anthropic, alleging that the company’s Claude Max subscriptions provide far less access than users were promised. The complaint, which seeks class-action status for U.S. consumers who bought a Max subscription since Anthropic began selling those tiers last year, claims the effective caps for the Max 5x and Max 20x options wind up below what Anthropic markets across its site and other materials. Kahn argues that "the actual usage provided by the Max 5x and Max 20x plans is far below the advertised amount of usage," citing his own experience after upgrading to Max 20x in April, where he still ran into weekly ceilings quickly, including a five-hour stretch that consumed 15% of his weekly allotment. Anthropic sells three paid plans for individuals, including Claude Pro starting at $17 per month, and later added Max plans priced at $100 and $200 per month, which it says can provide up to 5x and 20x the Pro plan's limits. Anthropic declined to comment on the case.
