Anthropic is facing a lawsuit from a Claude subscriber, Washington DC resident Karl Kahn, who alleges the company misled customers about the usage limits of its premium Claude Max subscription plans. The lawsuit claims that "the actual usage provided by the Max 5x and Max 20x plans is far below the advertised amount of usage." Anthropic introduced the Max 5x and Max 20x plans in April 2025, costing $100 and $200 per month respectively, which the company says offer up to five times and 20 times higher usage limits than the Pro plan. Kahn upgraded to the Max 20x plan after using Claude Code and claims he quickly ran into weekly usage restrictions; according to the lawsuit, one coding session lasting about five hours consumed 15 percent of his entire weekly allowance. The lawsuit seeks class-action status on behalf of other US customers who purchased a Claude Max subscription since the plans were launched. Separately, Anthropic pulled access to its Claude Fable 5 and Mythos 5 models globally due to an export control order issued by the US government.
