Claude Max 20x is now called Ultra, and verified Ultra accounts no longer have a 5-hour limit

New names, same prices

On Oct. 30, Anthropic announced on Claude’s X account that it is renaming its Max plans: Max 5x is now simply Max, and Max 20x is now Ultra. Prices are unchanged at $100 a month for Max and $200 for Ultra. The company says subscribers don’t need to do anything. According to the help center, Max 20x subscribers move to Ultra automatically, with no price change.

The bigger change is to usage limits. Anthropic is removing the 5-hour limit for verified Ultra accounts, starting the same day with most existing subscribers. Newer accounts keep a temporary limit until they are verified. The company says this helps prevent fraud and abuse, and users get an email when the limit is lifted.

We’re renaming our Max plans:

Max 5x → Max
Max 20x → Ultra

Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do.

We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed.

Weekly limits remain unchanged. View our plans here: claude.com/pricing

How verification works

According to the help center, Anthropic verifies Ultra accounts automatically, using factors like account and payment history, so users don’t need to take any action. Verifying a phone number at checkout is a separate step and does not remove the temporary limit. If no “Current session” bar appears under Settings > Usage, the account is verified.

Weekly limits still apply

Anthropic says weekly limits remain unchanged. The help center says Ultra includes 10 times the Pro plan’s usage every week, so the “20x” in the old name does not describe the weekly allowance. Ultra has a weekly limit that applies across all models and a separate weekly limit for the Fable model. According to the pricing page, Fable can use up to half of the weekly limit on Max and Ultra. Anthropic also says it may apply additional limits, such as weekly or monthly caps, to manage capacity.

Max keeps its 5-hour limit, offering five times Pro’s usage every five hours and every week. The pricing page also lists $200 a month in API credits for Ultra, compared with $100 on Max. Anthropic introduced API credits for subscribers in early October.

The “5x” and “20x” dispute

The multipliers have already drawn legal challenges in the U.S. According to Engadget, plaintiffs in a class action filed on Sept. 8 allege that the “5x” and “20x” comparisons describe only the session window that resets every five hours. They also argue that the weekly limits added in August 2025 were not clearly disclosed. A separate federal lawsuit was filed in June by a single subscriber. Anthropic has not linked the new names to either case.
