On June 15, Anthropic sent a notification to its subscribers, postponing the planned Claude developer quota reform that would have taken effect that day; CNET reported the same day that plaintiff Karl Khan filed a class action lawsuit in the U.S. District Court for the Northern District of California, alleging that Anthropic misled users about the actual usage limits of the Max 5x and Max 20x plans.
Anthropic Postponed Notification Content

According to the notice Anthropic sent to its subscribers, the decision to pause was made “to optimize the paid plans to better meet developers’ needs building applications with a Claude subscription.” The arrangements during the policy delay are as follows:
· All Agent SDK and CLI calls will continue to follow the existing web subscription rules; developers do not need to apply for any quotas
· Existing subscription limits remain unchanged
· Anthropic commits to notifying users in advance before the quota adjustment plans take effect in the future
The originally planned reform (now postponed): starting June 15, for Claude Agent SDK, single calls via the claude -p CLI, and third-party applications built on the Agent SDK, billing would switch to a fixed monthly quota model (Pro users get a $20 monthly quota; amounts exceeding that would be billed via the API).
Class Action Confirms Allegations: Claimed Multiples vs. Actual Usage Differences
Based on the complaint documents, Max 20x (a $200 monthly fee) is claimed to provide a 20x usage cap for the Pro plan, but the lawsuit alleges the actual cap is only 6 to 8x; Max 5x ($100 monthly) is claimed to be 5x, but the actual is only about 3.5x; the Pro plan monthly fee ranges from $17 to $20.
The complaint also accuses Anthropic’s website of “like a black box, with no clear explanation of how usage is calculated”; Anthropic has not clearly defined the meaning of “a single session”; and Anthropic, in its blog, reserves the right to “decide on other ways to limit usage (e.g., weekly and monthly caps, or limiting the use of models and features).”
The lawsuit seeks class action status, representing all users who purchased and used Max 5x or Max 20x since April 2025.
Usage Experience Confirmed by Plaintiff Karl Khan
In April 2026, plaintiff Karl Khan upgraded his subscription to the Max 20x plan twice for programming work. He found that in a single 5-hour coding sprint, he could consume nearly 20% of the weekly allowance, and after comparing different tiers, concluded there is a discrepancy between the advertised promotion and the actual usage-rate limitations. The lawsuit documents cite testimony from multiple dissatisfied users and point out that at least one popular Reddit post surprised many subscribers who felt the usage bottleneck; the original post author said the premium tier “is highly misleading.”
Frequently Asked Questions
Why did Anthropic postpone the quota reform for Agent SDK?
According to the notice sent by Anthropic to users, the decision to pause was made “to optimize the paid plans to better meet developers’ needs building applications with a Claude subscription.” The specific adjustment direction and the new effective time have not been announced yet; Anthropic has promised to notify users in advance before the new policy takes effect.
What exactly is the “multiple” dispute in the Karl Khan lawsuit?
According to the complaint documents, Anthropic claims that the Max 20x plan provides a 20x usage cap of the Pro plan, and that Max 5x provides 5x. But the lawsuit alleges that the actual usage cap of Max 20x is only 6 to 8x, and Max 5x is only about 3.5x. The complaint describes Anthropic’s website and blog as providing insufficient usage-calculation explanation, calling it a “black box.”
What are the eligibility requirements for this class action?
According to the complaint documents, eligibility to join the class action is for users who have purchased and used the Anthropic Max 5x or Max 20x subscription plans since April 2025. The disputed amount exceeds $5 million (excluding attorney’s fees). The lawsuit is still in early proceedings, and Anthropic has not yet responded.
