The artificial intelligence company Anthropic is facing a newly proposed class action lawsuit that alleges it’s misleading subscribers over plan usage limits for Claude. Claude is an AI assistant designed for coding, writing, research and data analysis.
The suit alleges that the actual rate limits imposed on subscribers to the two most expensive paid tiers, the Max 5x and Max 20x, are far below what the company advertises. Usage limits, according to Anthropic, refer to how much users can work with Claude during a specific window of time, like a “conversation budget.”
The complaint argues that the real usage cap for the 20x, which costs $200 per month and promises 20 times the usage cap of the Pro package, amounts to “just six to eight times the usage of Pro.” The Max 5x plan, which costs $100 per month, purportedly delivers “just three-and-a-half times the usage of Pro” instead of the promised five times. The Claude Pro subscription tier costs between $17 and $20 per month.
The plaintiff, Karl Khan, filed the suit in the US District Court for the Northern District of California on Sunday. Khan first tinkered with Claude for personal reasons before deciding to use it for coding work, upgrading his subscription twice to the Max 20x plan by April 2026.
He quickly found he was frequently using up nearly 20% of his weekly data allocation in a single 5-hour-long coding sprint. Khan compared his experience across the different subscription tiers and concluded that there was a discrepancy between the advertising and the reality of Claude’s usage rate limits.
Even as concerns proliferate about the rising costs of AI model subscriptions and the lack of transparency of AI usage limits for commercial customers, several of the Claude models continue to be adopted by programmers and so-called vibe coders.
The Trump administration recently banned foreign governments and companies from using Anthropic’s most powerful AI tools and has temporarily shut down entire…
