A Claude subscriber has sued Anthropic, alleging the corporate mislead customers in regards to the utilization limits of its Max plans. Per The Wall Street Journal, Karl Kahn, a Washington DC-based resident, filed a federal lawsuit on Monday accusing Anthropic of overselling how a lot he may use Claude. The lawsuit claims that the precise utilization caps of Anthropic’s Max 5x and Max 20x tiers are onerous to find out and seem decrease than the bounds the corporate advertises on its website and elsewhere.
Anthropic presents three completely different paid tiers for people. The corporate’s most reasonably priced plan, Claude Professional, begins at $17 per 30 days and “presents not less than 5 occasions the utilization per session in comparison with our free service” throughout peak hours. “The variety of messages you may ship will fluctuate based mostly on message size, together with the size of recordsdata you connect, the size of your present dialog, and the mannequin or function you employ,” Anthropic writes on its website. Since April 2025, the corporate has additionally supplied Max 5 and 20x plans, which promise as much as 5 and 20 occasions greater utilization caps than the Professional package deal. The 2 plans price $100 and $200 per 30 days, respectively.
“The precise utilization supplied by the Max 5x and Max 20x plans is way beneath the marketed quantity of utilization,” the lawsuit alleges. After he started utilizing Claude Code, Khan upgraded to the Max 20x plan in April of this 12 months, however shortly discovered himself hitting his weekly utilization limits. One five-hour session noticed him undergo 15 p.c of his weekly allowance. The lawsuit is in search of class action-status on behalf of different US customers who bought a Max subscription since Anthropic started providing them final 12 months.
Anthropic declined to remark.
Anthropic’s price limits are a frequent matter of dialogue on Reddit, with one person just lately complaining about how they blew previous their five-hour restrict after just a single Claude Code prompt. Final July, the corporate imposed weekly rate limits on Claude Code utilization in response to customers who had been working the coding agent “repeatedly within the background, 24/7.”
All massive language fashions function on a foreign money often known as tokens. Whenever you sort a query into Claude’s immediate bar, it converts phrases, teams of characters and punctuation into numbers that map to completely different patterns and relationships Anthropic’s fashions discovered in coaching. For a mannequin to generate a response, there are each enter and output prices, and people can fluctuate vastly relying on the complexity of a immediate.
The lawsuit highlights a long-growing disconnect between shopper expectations and the precise price of offering AI inference. Conventional software program subscription fashions do not map neatly, if in any respect, to how a lot compute LLMs require to work at scale. Proper now, enterprise capitalists are offsetting these prices, and if something, the issue is prone to turn out to be extra acute when Anthropic and OpenAI go public.
