Anthropic says Claude's Ultra plan did not lose capacity in its rename

What changed in the plan names

Anthropic, the maker of the AI assistant Claude, renamed two of its paid plans. Max 5x became Max, and Max 20x became Ultra. The prices did not change.

The Ultra plan also lost its 5-hour limit, a cap on how much you can use Claude within one five-hour session. Its description now says it gives 10 times the usage of the Pro plan.

Why users thought capacity was halved

The old name promised 20x. The new description says 10 times. As itmedia.co.jp reported, many users on X read that as a cut in half, with no change in price.

Anthropic's explanation

Anthropic's head of product says the '20x' label dates from a time when only the 5-hour limit existed. It meant 20 times Pro's allowance in a single session.

Later, the company added a weekly limit to Max 20x and set it at 10 times Pro's. With the 5-hour cap now gone from Ultra, the weekly limit is the only one left, so the page describes just that one.

Where the old page fell short

An earlier version of the pricing page said Max offered 5 or 20 times Pro's usage. Its FAQ explained that this applied per 5-hour session, that paid plans also have weekly limits, and that Anthropic may restrict use to manage capacity.

What it did not say was that Max 20x's weekly limit was 10 times Pro's. The product head acknowledged that some new users assumed 20x applied to both limits, and he apologised.
