Amid the fierce competition in AI large models, users' expectations for paid subscription services are constantly rising. However, the artificial intelligence company Anthropic has recently been caught in a trust crisis. According to a consumer named Karl Kahn from Washington D.C., the company's premium subscription service, the Claude Max plan, is suspected of severely overstating its usage limits, with the actual interactive quota far below what is officially advertised.

It is known that this dispute mainly focuses on two high-end subscription plans launched by Anthropic: the "Max5x" plan priced at $100 per month and the "Max20x" plan priced at $200 per month. According to official promotions, these plans are intended to provide heavy users with significantly better usage quotas than the standard version (Pro plan), increasing them by 5 to 20 times. However, Kahn believes there is a huge gap between this promotion and the user's actual perception, and for ordinary consumers, it is almost impossible to intuitively measure how much actual computing power they have received.

In the eyes of this consumer, this discrepancy constitutes a misguidance to users. Currently, Kahn has filed a lawsuit in court and has requested that Anthropic be forced to refund affected subscription users. More problematically, he is actively pushing to escalate the case into a class-action lawsuit, aiming to involve more users who feel that the product does not match the description.
