A California lawsuit, filed this week by Washington, D.C. customer Karl Kahn, alleges Anthropic oversells usage for its priciest Claude subscription tiers. The complaint targets the Claude Max “5x” plan, priced at $100 per month, and the Claude Max “20x” plan, priced at $200 per month, which the company markets as delivering five and 20 times the usage compared with a baseline tier. According to the allegations described across multiple outlets, customers receive far less usage than advertised. The lawsuit is proposed as a class action and asks a court to require Anthropic to make customers whole. Specific requested remedies are not detailed in the excerpts, but the filings seek court intervention over the alleged mismatch between promised and delivered usage and claim customers were misled about the value of the plans. The reporting does not include a response from Anthropic in the provided material.
